DETAILED DESCRIPTION OF THE INVENTION

For the present patent application, a shaft always comprises an axis. A shaft can have different shapes at different sections. The shape of a cross section of a shaft can be round or rectangular, or of other shape. A bearing, except linear motion bearing, comprises an inner ring and an outer ring, and possibly other parts. One or more bearings are said to connect a shaft and a bearing housing, if the inner rings of the bearings are fixedly connected to the shaft and the outer rings of the bearings are fixedly connected to the bearing housing, so that the shaft is constrained to rotate relative to the bearing housing around the axis of the shaft. Such a connection of a shaft and a bearing housing by one or more bearings, should also include accessories; but for simplicity, we may or may not mention the accessories. It should be noted that there are many ways of installing one or more bearings connecting a shaft and a bearing housing. For example, the inner ring(s) of the bearing(s) may be fixedly connected to (and concentric with) the shaft, and the outer ring(s) of the bearing(s) may be fixedly connected to (and concentric with) the bearing housing. A bearing may be a ball or roller bearing, or of other type. In some applications, two or more bearings of the same or distinct types are configured to connect a shaft and a bearing housing. For the present patent application, a rotational movement refers to a rotational movement around an axis.

For the present patent application, a motor comprises a stationary member, a moving member, and a powered mechanism configured to produce a relative motion between the stationary member and moving member. A motor may be of different type depending on power source, e.g., electric, hydraulic, pneumatic, etc. A computer may be configured to control a motor, e.g. by controlling the timing, direction and speed of the motion of the motor. In many of the following applications, a motor comprises a base component (e.g., a frame) which is a stationary member of the motor, and a shaft which is a moving member of the motor, so that the powered mechanism of the motor can produce a rotation of the shaft relative to the base component around the axis of the shaft.

Our cooking system comprises a computer and several apparatuses and mechanisms, including a cooking apparatus, a receiving apparatus, a transfer apparatus, a dispensing apparatus, a cleaning apparatus, etc. Some of these constituents will be described first.

Referring to FIG. 1, a computer 901 comprises a plurality of i/o ports. The i/o ports 901 a can be connected to a plurality of electric or electronic devices, and to sensors. The computer 901 may send and receive electric or electronic signals to the connected electric or electronic devices and to sensors. The computer 901 may control the operations of the electrical or electronic devices by sending electric or electronic signals to the electrical or electronic devices.

Referring to FIGS. 2A-2B, a cooking container 100, positioned in the upright position, is configured to hold food or food ingredients for cooking. The cooking container 100 may have the shape of a wok which is rotationally symmetric around an axis, referred to as the axis of the cooking container 100. The axis of the cooking container 100 may be configured to be vertical or nearly vertical when the cooking container 100 is positioned in the upright position. The cooking container 100 also comprises a barrier 109 in the shape of a ring, on the bottom of the cooking container.

It should also be noted that it is not a strict requirement that the cooking container 100 to be rotationally symmetric around an axis. A cooking container may have other shape.

The cooking container 100 may further comprise one or more straight or curved ridges, on its bottom, as barriers. A barrier may make food ingredients (in the cooking container) jump when the cooking container is fast moved horizontally, or in some other directions.

Referring to FIGS. 2C-2D, a connecting component 113 is comprised of a deformed metal sheet, including a flat part 113 a, and a curved part 113 b. The curved part 113 b has some oval shaped holes. The flat part 113 a has some round holes 113 d. The flat part 113 a and the curved part 113 b may be both ring-shaped, although this is not a requirement. As shown in FIG. 2D, the flat part 113 a of the connecting component 113 comprises a lower surface 113 ax which is flat.

Referring to FIG. 2E, a cooking device 101 a comprise the cooking container 100 and the connecting component 113, whereas the curved part 113 b is welded to the cooking container 100. The flat surface 113 ax of the connecting component 113 is configured to be horizontal when the cooking container 100 is in the upright position. Both the curved part 113 b and the flat part 113 a of the connecting component 113 are ring-shaped objects with holes which surround the cooking container 100, The flat surface 113 ax is a ring-shaped surface with holes which surround the cooking container 100.

It should be noted that, without counting the holes, the ring-shaped objects 113 a and 113 b are perfectly round, but they may be substituted with other ring-shaped objects with holes surrounding the cooking container 100, where the “ring-shapes” are ring-shapes in topological sense. In the present patent application, “ring-shape” is meant ring-shape in topological sense.

It should be noted that the oval shaped holes in the connecting component 113 are not always needed. The presence of the oval shaped holes may possibly help with better welding between the cooking container 100 and the connecting component 113. The presence of the oval holes may also help reduce the weight in the cooking device 101 a.

Referring to FIG. 2F, a flat board 112 comprises some round holes wherein the diameter of the said round holes are about the same as the diameter of the round holes 113 d on the flat part 113 a of the connecting component 113. The flat board 112 comprises an upper surface 112 x which is flat.

Referring to FIG. 2G, a cooking device 101 comprises: the cooking device 101 a; bearing housings 115 and 116; and a flat board 112. The bearing housings 115 and 116 are rigidly connected to the flat board 112. The rigid connection may be achieved by bolts and nuts, or by other means. Furthermore, the flat part 113 a of the connecting component 113 of the cooking device 101 a is configured to be rigidly connected with a ring-shaped area of the flat board 112 via a plurality of bolts 114 and corresponding nuts. The bolts 114 are inserted through the round holes 113 d of the component 113 and the round holes of the flat board 112. The surfaces 113 ax and 112 x are configured to be horizontal, and hence parallel to each other. The surfaces 113 ax and 112 x may either touch each other or be separated by a ring-shaped heat-insulation flat board with holes.

The flat board 112 may be referred to as a holder, or a holding part. In the cooking device 101, the holder 112 is rigidly connected with the cooking container 100, if ignoring the elastic or other deformations. The flat board 112 may be made of steel or aluminum alloy or other metal, carbonate fiber, durable plastic, or other durable material. The flat board 112 may be substituted by a solid component of a different shape.

The flat part 113 a may be placed either above or below the holding part 112.

The rigid connection of the flat board 112 with the cooking container 100 may be substituted by a different type of connection, such as an elastic connection comprising springs or other elastic devices, a connection comprising one or more kinematic pairs, etc.

It should also be noted that the bearing housings 115 and 116 may each comprise a flange configured to be rigidly connected with the flat board 112 by a plurality of bolts and nuts. The techniques of using bolts and nuts to rigidly connect these are well-known.

It should also be noted that heat insulation materials may be inserted to separate the flat part 113 a and the holder 112.

The cooking container 100 may be configured to have a flat edge on top, e.g., a circle, which may be configured to be horizontal when the cooking container is positioned in the upright position.

Referring to FIGS. 3A-3F, a cooking sub-apparatus 110 comprises: the cooking device 101; a pair of holed cylinders 121 and 123 which are rigidly connected to a connector 122 (see FIG. 3A); two shafts 125 and 126 (see FIG. 3B). The cooking sub-apparatus 110 also comprises two bearing housings 124 a and 124 b and a half-circular board 124 c all of which are rigidly connected to a connector 124 d, wherein the connector 124 d may optionally have the shape of a partial holed cylinder. The axes of the bearing housings 124 a and 124 b are configured to be identical. The shaft 125 is rigidly connected with the holed cylinder 121 wherein the shaft 125 is inserted in the hole of the holed cylinder 121; and the shaft 126 is rigidly connected with the holed cylinder 123, wherein the shaft 126 is inserted in the hole of the holed cylinder 123. A bearing 127 and accessories are configured to connect the shaft 125 and the bearing housing 124 a and another bearing and accessories (hidden in figure) are configured to connect the shaft 125 and the bearing housing 124 b, so that shaft 125 is constrained to rotate relative to the bearing housings 124 a and 124 b, around the axis of the shaft 125.

The cooking sub-apparatus 110 further comprises: a first support component 226 in the shape of a board wherein the first support component 226 comprises two sub-components 226 a and 226 b; a bearing housing 224; two flanges 224 a and 224 b which are rigidly extended from the bearing housing 224; a shaft 132, referred to as a main shaft; and a shaft 131, referred to as an eccentric shaft (see FIGS. 3C-3D). The main shaft 132 and the eccentric shaft 131 are rigidly connected to each other. The component 124 c is rigidly connected to the first support component 226. The flange 224 a is configured to be rigidly connected with the first support component 226; and hence the bearing housing 224 is rigidly connected with the first support component 226. A pair of bearings 225 (and accessories) are configured to connect the main shaft 132 and the bearing housing 224, so that the main shaft 132 is constrained to rotate relative to the bearing housing 224 around the axis of the main shaft 132. Thus, the eccentric shaft 131 is constrained to rotate around the axis of the main shaft 132, relative to the bearing housing 224, and equivalently, relative to the first support component 226. In other words, the eccentric shaft 131 is constrained to make an eccentric rotation, where the axis of the rotation is not identical to the axis of the eccentric shaft.

The axes of the shafts 125, 126, 132 and 131 may be parallel to each other, and the distance between the axis of the main shaft 132 and the axis of the eccentric shaft 131 is configured to be strictly less than the distance between the axis of the shaft 126 and the axis of the shaft 125. The distance between the axes of the shafts 132 and 131 is relatively small, usually not exceeding tens of millimeters. Although this is not a strict requirement, the axes of the shafts 131, 132, 125 and 126 are configured to be vertical and the top surface of the first support component 226 is configured to be horizontal, when the cooking container 100 is at the upright position.

The cooking sub-apparatus 110 further comprises: a motor 92A comprising a base component and a shaft; a connecting component 223; and a coupling 222. The base component of the motor 92A is rigidly connected to the connecting component 223. The connecting component 223 is rigidly connected to the flange 224 b, and thus is rigidly connected with the first support component 226. The shaft of the motor 92A is fixedly connected to the main shaft 132 by the coupling 222. Thus, the motor 92A may drive the rotation of the main shaft 132, and hence the eccentric shaft 131 is rotated around the axis of the main shaft 132. The motor 92A is connected to the computer 901 via wires 94A. The computer 901 may be configured to send electric or electronic signals to the motor 92A as to dynamically control the timing and/or speed of the motor 92A (or indirectly the angle of rotation of the main shaft 132) The cooking sub-apparatus 110 further comprises: a pair of bearings 117 (and accessories) configured to connect the eccentric shaft 131 and the bearing housing 115, so that the eccentric shaft 131 is constrained to rotate relative to the bearing housing 115 around the axis of the shaft 131; a bearing 118 (and accessories) is configured to connect the shaft 126 and the bearing housing 116, so that the shaft 126 is constrained to rotate relative to bearing housing 116 around the axis of the shaft 126 (see FIGS. 3E-3F). When the main shaft 132 is rotated around the axis of the main shaft 132 by the motor 92A, the eccentric shaft 131 makes an eccentric rotation around the axis of the main shaft 132. This produces a cyclic, planar movement in the holder 112 and in the cooking container 100, if ignoring elastic and other deformations. The movement in the cooking container 100 may stir, mix and distribute the food or food ingredients contained in the cooking container 100. The cooking sub-apparatus 110 also comprises two proximity switches 91A and 91W both of which are fixedly connected to the connecting component 223, a target 132 a with a rectangular cross section, and a target 132 b in the shape of a hemi-discoidal. The targets 132 a and 132 b are fixedly connected to the main shaft 132. The proximity switch 91A and 91W are connected to the computer 901 separately via wires 93A and 93W. The proximity switch 91A senses the target 132 a when the target 132 a is rotated with the main shaft 132. The proximity switch 91W senses the target 132 b when the target 132 b is rotated with the main shaft 132. When one of the proximity switches 91A and 91W separately senses the targets 132 a and 132 b, the electric or electronic signals of the proximity switches 91A and 91W are sent to the computer 901. The computer 901 can figure out the position of the target 132 a or 132 b, and the position of the main shaft 132.

As shown in FIGS. 3E-3G, the motor 92A is connected to the computer 901 via wires 94A. The computer 901 may be configured to send electric or electronic signals to the motor 92A as to dynamically control the timing and/or speed of the motor 92A; where the speed of the motor 92A may be variable over time, per recipe. As shown in FIG. 3H, the proximity switches 91A and 91W are also connected to the computer 901 separately via wires 93A and 93W, so the computer 901 may receive electric or electronic signals from the switches 91A and 91W.

Referring to FIGS. 3G-3I, the cooking sub-apparatus 110 further comprises some accessories: lockouts 138 and 149, a ring 139 and a sleeve 229 wherein these accessories are not shown in other figures. The pair of bearings 117 which are configured to connect the eccentric shaft 131 and the bearing housing 115 may be substituted by a pair of angle contact ball bearings 117 a or a pair of tapered roller bearings 117 b. Similarly, the pair of the bearings 225 which are configured to connect the main shaft 132 and the bearing housing 224 may be substituted by a pair of angle contact ball bearings 225 a or a pair of tapered roller bearings 225 b or (see FIGS. 3H-3I). The locknut 138 and the ring 139 are used to separately fix the inner ring and outer ring of the upper angle contact ball bearings 117 a or the upper tapered roller bearings 117 b. The locknut 149 is used to fix the inner ring of the lower angle contact ball bearing 225 a or the lower tapered roller bearing 225 b. The sleeve 229 is on the main shaft 132 and is positioned between the two angle contact ball bearings 225 a or tapered roller bearings 225 b.

It should be noted that the angle contact ball bearings and the tapered roller bearings are used in situations of high speed and high precision, and both of the angle contact ball bearings and the tapered roller bearings have superior performance in bearing axial force. The angle contact ball bearings or the tapered roller bearings are usually configured to be paired mounting.

It should be noted that the bearing 118 which is configured to connect the shaft 126 and the bearing housing 116 may be substituted by a self-aligning ball bearing. Since the axis of the inner ring of the self-aligning ball bearing may tilt relative to the axis of the outer ring of the self-aligning ball bearing in a certain range, the self-aligning ball bearings may adjust the axis of the inner ring being concentric with that of the shaft 126 even if the axis of the shaft 126 is not entirely concentric with the axis of the bearing housing 116 by vibrations, errors or allowances.

It should be noted that the cooking sub-apparatus 110 comprises: the cooking device 101 comprising a cooking container 100 configured to hold food or food ingredients; and a stirring motion mechanism configured to produce a cyclic motion in the cooking device 101 and hence the stirring motion mechanism configured to produce a cyclic motion in the cooking container 100 as stir, mix or distribute the food or food ingredients contained in the cooking container 100. The said stirring motion mechanism comprises:

(8) a fourth connection comprising the bearings 127 (and accessories) configured to connect the second main shaft 125 of the third link and the bearing housings 124 a and 124 b of the fourth link, so that the third link is constrained to rotate relative to the fourth link around the axis of the second main shaft 125;

(9) a motion mechanism configured to produce a rotation in the first main shaft 132 (of the second link) around the axis of the first main shaft 132 wherein the motion mechanism comprises the motor 92A, the proximity switches 91A and 91W, the targets 132 a and 132 b, the fixed connection of the base component of the motor 92A with the first support component 226, and the connection of the shaft of the motor 92A with the first main shaft 132, etc.

It should be noted that the first connection discussed above connects the first link and the second link, so that the first link is constrained to rotate relative to the second link; the second connection connects the second link and the fourth link so that the second link is constrained to rotate relative to the fourth link; the third connection connects the first link and the third link, so that the first link is constrained to rotate relative to the third link; the fourth connection connects the third link and the fourth link, so that the third link is constrained to rotate relative to the fourth link; the motion mechanism produces a motion of the second link relative to the fourth link.

It should also be noted that the above stirring motion mechanism comprises a crank-rocker mechanism comprising: the first link, second link, third link, fourth link, the first connection, the second connection, the third connection and the fourth connection.

It should be noted that the stirring motion mechanism comprises: (1) a first rotational mechanism comprising the second eccentric shaft 126, the bearing housing 116, and a connection comprising the bearing 118 configured to constrain the relative movement of the second eccentric shaft 126 and the bearing housing 116 to an axial rotation; (2) a second rotational mechanism comprising the first eccentric shaft 131, the bearing housing 115, and a connection comprising the bearing 117 configured to constrain the relative movement of the first eccentric shaft 131 and the bearing housing 115 to an axial rotation; (3) a third rotational mechanism comprising the first main shaft 132, the bearing housing 224, and a connection comprising the bearing 225 configured to constrain the relative movement of the first main shaft 132 and the bearing housing 224 to an axial rotation; (4) a fourth rotational mechanism comprising the second main shaft 125, the bearing housings 124 a and 124 b, and a connection comprising the bearings 127 configured to constrain the relative movement of the second main shaft 125 and the bearing housing 124 a and 124 b to an axial rotation; (5) the support component 226; (6) the holed cylinders 121 and 123, the connector 122, the motor 92A, the coupling 222, the connecting component 223; (7) the mutual connections among the above parts, if any.

The support component 226 is referred to as the support component of the stirring motion mechanism, and the stirring motion mechanism produces a planar movement in the cooking container 100 relative to the support component 226. Although this is not a strict requirement, the magnitudes of movements of points on the cooking container may be configured to be in tens of millimeters, anywhere from 10 to 99 millimeters.

The rigid connection of the holder 112 (or of the first link) with the cooking container 100 may be substituted by a flexible connection or other types of connection. The first link, second link, third link or fourth link described above may be substituted by a first solid component, a second solid component, a third solid component and respectively a fourth solid component. A solid component may comprise a rigid part or rigid component, or an elastic part or elastic component, or both rigid and elastic parts.

It should be noted that the axes of the first main shaft 132 and the first eccentric shaft 131 may be configured to parallel to each other. The distance between the two parallel axes may be kept fixed in some applications or adjustable in some other applications; where the distance may further be configured to be properly small (less than tens of millimeters).

It should be noted that the axes of the shafts 131, 132, 126 and 125 in the cooking sub-apparatus 110 may be configured to intersect at a same point, instead of being configured to be parallel to each other; and the angle between the axes of the shafts 131 and 132 is configured to be smaller than the angle between the shafts 126 and 125. The angle between the shafts 131 and 132 may be quite small, no more than several degrees in many applications. In this case, the stirring motion mechanism in the cooking sub-apparatus 110 produces a cyclic, spherical motion in the cooking container 100 and the holder 112, if ignoring elastic and other deformations.

Referring to FIGS. 4A-4B, a motion mechanism 104 comprises: a cam 134 comprising a curved track, wherein the cam has a shape of a board and the curved track is a curved hole of a certain width on the board; and a bearing housing 133 (with a flange and a base rigidly attached to it); a shaft 158; a connecting component 156; a coupling 157; and a motor 92B comprising a shaft and a base component. The cam 134 is rigidly connected to the shaft 158. A pair of bearings and accessories (hidden in figure) are configured to connect the shaft 158 and the bearing housing 133, so that the shaft 158 is constrained to rotate relative to the bearing housing 133, around the axis of the shaft 158. The connecting component 156 is configured to fixedly connect the bearing housing 133 and the base component of the motor 92B. The shaft of the motor 92B is connected to the shaft 158 by the coupling 157. Thus, the motor 92B may drive the rotation of the shaft 158, and hence the cam 134 is rotated around the axis of the shaft 158. The curved track of the cam 134 has a curved profile comprising a circular arc at either end of the curved profile; wherein each circular arc is a part of a circle centered at the axis of the shaft 158. The edge of the curved track of the cam 134 comprises equidistant curve to the curved profile.

The motion mechanism 104 also comprises a proximity switch 91B; a connecting component 159 configured to fixedly connect the proximity switch 91B to the bearing housing 133; and two targets 137 a and 137 b both of which are fixedly joined with the cam 134. As shown in FIG. 4B, the motor 92B is connected to the computer 901 via wires 94B. The computer 901 is configured to dynamically control the timing and/or speed of the motor 92B. The proximity switch 91B is also connected to the computer 901 via wires 93B, so the computer 901 may receive electric or electronic signals from the proximity switch 91B. The proximity switch 91B senses the targets 137 a and 137 b when the targets 137 a and 137 b are rotated with the cam 134. When the cam 134 is rotated to a first position (or second position) where the proximity switch 91B senses the target 137 a (or respectively 137 b), the electric or electronic signals are sent to the computer 901. The computer 901 can figure out the position of the target 137 a (or respectively 137 b), and the position of the cam 134. Then the computer 901 can send electric or electronic signals to the motor 92B as to control the rotation of the motor 92B for a time period during which the motion mechanism 104 can complete a corresponding process. After this time period, the motor 92B, under the control of the computer 901, may restart again and make a reverse rotation to rotate the cam 134 to the second position or respectively the first position.

Referring to FIGS. 4C-4H, a cooking apparatus 120 comprises the cooking sub-apparatus 110 and a cooking container unloading mechanism, wherein the said cooking container unloading mechanism comprises: a support component 175 in the shape of a board; a pair of shaft seats 161 and 163; and a shaft 162; wherein the shaft seats 161 and 163 are configured to rigidly connect the shaft 162 to the support component 175 (see FIG. 4C). The said cooking container unloading mechanism further comprises: bearing housings 227, 228 a and 228 b; a rigid connection of the bearing housings 227, 228 a and 228 b to the first support component 226; a shaft 231; and bearings 232 (and accessories) configured to connect the shaft 231 and the bearing housing 227, so that the shaft 231 is constrained to rotate relative to the bearing housing 227, around the axis of the shaft 231 (see FIGS. 4D-4E). The axes of the bearing housings 228 a and 228 b are configured to be coincide; and the axes of the bearing housings 227, 228 a and 228 b are configured to be parallel to a same horizontal direction.

The said cooking container unloading mechanism of the cooking apparatus 120 further comprises: the motion mechanism 104; a weight 164; a connector 176 configured to connect the weight 164 to the first support component 226 of the cooking sub-apparatus 110; two roller bearings (hidden in figures) configured to connect the shaft 162 and the bearing housing 228 a and 228 b respectively, so that the shaft 162 is constrained to rotate relative to the bearing housings 228 a and 228 b, around the axis of the shaft 162 (see FIGS. 4F-4H). Thus, the first support component 226 of the cooking sub-apparatus 110 is constrained to rotate relative to the shaft 162 (or equivalently, relative to the support component 175), around the axis of the shaft 162. The axis of the shaft 231 of the cooking sub-apparatus 110 is configured to be parallel but not identical to the axis of the shaft 162. The bearing housing 133 of the motion mechanism 104 is configured to be rigidly connected to the support component 175 (although the connection is not shown in figures). The axis of the shaft 158 is configured to be parallel but not identical to the axis of the shaft 162. The axes of the shafts 158, 162 and 231 are configured to be never co-planar. In fact, the distance between the axes of the shafts 162 and 231 is usually smaller than the distance between the axes of the shafts 162 and 158; and the distance between the shafts 231 and 158 is variable. The shaft 231 is configured to be inserted into (and be constrained by) the curved track of the cam 134 of the motion mechanism 104. As explained, the edge of the curved track of the cam 134 comprises equidistant curve to the curved profile of the cam 134. The distance of the said edge to the said curved profile is configured to be equal to (or slightly larger, usually by 0.1 mm or lesser, than) the radius of the shaft 231 in the section constrained by the curved track of the cam 134. It should be noted that the shaft 231 may be considered as a wheel which is rotatable relative to the bearing housing 227; and since the bearing housing 227 is rigidly connected to the first support component 226, the shaft 231 is rotatable relative to the support component 175, around the axis of the shaft 162. Thus, a movement of the axis of the shaft 231 may produce a rotation of the first support component 226 around the axis of the shaft 162.

As explained earlier, the curved track of the cam 134 comprises two circular profiles next to the two ends, along circles centered at the axis of the shaft 158. When the shaft 231 is constrained by any one of the circular profiles of the curved track, the distance between the axes of the shafts 231 and 158 may stay constant, and the axis of the shaft 231 may not move relative to the axes of the shafts 162 and 158. When the shaft 231 is constrained by the non-circular profiles of the curved track of the cam 134, the axis of the shaft 231 is moved relative to the axes of the shafts 162 and 158, as the distance between the axes of the shafts 231 and 158 is changed. The motor 92B of the motion mechanism 104 may produce a rotation of the cam 134 around the axis of the shaft 158. The rotation of the cam 134 induces a movement of the shaft 231. The movement of the shaft 231 induces a rotation of the first support component 226 of the sub-apparatus 110 relative to the support component 175. The rotation of the first support component 226 induces a turning in (the sub-apparatus 110 and) the cooking container 100, around the axis of the shaft 162. Moreover, the said cooking container unloading mechanism may be configured to move the first support component 226 from a first end position where the cooking container 100 is positioned upright and able to hold food or food ingredients for cooking, to a second end position so that a cooked food in the cooking container 100 may be unloaded from the cooking container 100. It should be noted that when the first support component 226 is rotated to the first end position (or second end position), the cam 134 of the motion mechanism 104 is rotated to the corresponding position where the proximity switch 91B senses the target 137 a (or 137 b). At the same time the computer 901 may send signals to the motor 92B as to control the rotation of the motor 92B for a time during which the cooking sub-apparatus 110 may complete a cooking process (or respectively unloading process). The range of angular rotation of the first support component 226 around the axis of the shaft 162, between the two end positions, may be configured to be an angle between 90 and 180 degrees (often between 120 to 150 degrees), although this is not a strict requirement. The weight 164 is configured to balance the sub-apparatus 110, so that the center of the gravity of the whole of the sub-apparatus 110 and the weight 164 is located at or near the axis of the shaft 162; and, as consequence, it does not require too much power for the motor 92B to produce a rotation in the first support component 226.

The cooking apparatus 120 also comprises a heating device 168, one or more temperature sensors 91C, and a fan 167. The heating device 168 is mounted on a plastic component 172 which is rigidly connected to the support component 175 by connectors 165 and 166. The temperature sensors 91C are fixedly connected to the plastic component 172 via connecting components (see FIG. 4C, also see FIG. 4H). The heating device 168 comprises an inductive stove configured to generate oscillating magnetic fields as to heat the ferromagnetic material of the cooking container 100, when the first support component 226 is position at the first end position. The inductive stove comprises coils (made by copper or other material). The temperature sensor 91C are configured to detect the temperature of the heating device 168. The fan 167 is configured to produce air flow as to cool the heating device 168. The fan 167 is mounted on aboard 169 which is connected to the connectors 165 and 166. As shown in FIG. 4C, the heating device 168 are connected to the computer 901 via wires 93Z. The computer 901 is configured to dynamically control the power and/or time of the heating device 168; where the temperature of cooking may be different in different recipe. The temperature sensor 91C is also connected to the computer 901 via wires 93C, so the computer 901 may receive electric or electronic signals from the temperature sensor 91C. When the computer 901 receives electric or electronic signals from the temperature sensor 91C and the signals show that the temperature of the heating device 168 is beyond (or below) the designed temperature range during a cooking process, the computer 901 may send signals to control the heating device 168 to increase (or respectively reduce) the power of oscillating magnetic fields to keep the temperature in the range.

It should be noted that the shaft 162 of the cooking apparatus 120 may be configured to be horizontal.

The support component 175 in the cooking apparatus 120 may be referred to as a second support component of the cooking apparatus 120. As explained before, the support component 226 is referred to as a first support component.

It should be noted that the cooking apparatus 120 comprises: the cooking sub-apparatus 110 comprising the cooking container 100, and the stirring motion mechanism comprising the first support component 226, wherein the stirring motion mechanism is configured to produce a cyclic planar motion in the cooking container 100 relative to the first support component 226, as to stir, mix or distribute the food or food ingredients contained in the cooking container 100; the heating device 168 and the fan 167, wherein the heating device 168 is mounted on the plastic component 172, wherein the plastic component 172 is rigidly connected to the second support component 175, wherein the heating device 168 is configured to heat the cooking container 100 during a cooking process.

It should also be noted that the cooking apparatus 120 further comprises the second support component 175, and the cooking container unloading mechanism configured to rotate (or otherwise move) the first support component 226 relative to the second support component 175 around the axis of the shaft 162 between a first end position and a second end position, and hence the cooking container 100 is rotated relative to the second support component 175 around the axis of the shaft 162 between a first end position and a second end position. In the first end position, the first support component 226 is so positioned that the cooking container 100 is positioned upright as to be able to hold food ingredients (as seen in FIG. 4G); and when the first support component 226 is rotated to the second end position, the cooking container 100 is turned as to be able to dispense cooked food from the cooking container 100 (as shown in FIG. 4H). From the first end position to the second end position, the axis of the cooking container 100 is turned by a certain fixed angle which can optionally be any constant chosen between 75 to 180 degrees, or in the most common applications chosen between 80 to 120 degrees.

It should be noted that the motion mechanism 104 of the cooking container unloading mechanism of the cooking apparatus 120 may be able to brake the rotation of the first support component 226 (around the axis of the shaft 162) relative to the second support component 175, when the first support component 226 is at the first end position relative to the second support component 175. As explained, the curve profile of the curved track of the cam 134 comprises a circular arc at either end; wherein each circular arc is part of a circle centered at the axis of the shaft 158 (FIGS. 4A-4B). During the time period when the shaft 231 is constrained by the curved track in the part corresponding to one of the circular arcs, the axis of the shaft 231 is not moved even if the cam is rotated around the axis of the shaft 158. The cam 134 may then be used as a braking device for the motion of the axis of the shaft 231 around the axis of the shaft 162, under the condition that the cam 134 is not forcefully moved by the motor 92B from a still position. In fact, the axis of the shaft 231 does not move, even if the cam 134 is slightly moved; the ratio of the speed of the rotational motion of the axis of the shaft 231 and the speed of the rotational motion of the cam 134 is zero, or equivalently, the ratio of the speed of the rotational motion of the cam 134 and the speed of the rotational motion of the axis of the shaft 231 is infinity. If the axis of the shaft 231 is not moved, then the first support component 226 cannot be rotated around the axis of the shaft 162, if not counting vibrations, errors or allowances.

The motion mechanism 104 of the cooking container unloading mechanism is able to brake the motion of the said first support component 226 relative to the said second support component 175 when the said first support component 226 is moved to the first position or second position relative to the said second support component 175.

It should be noted that when the proximity switch 91B senses the target 137 a or 137 b, the cam 134 are rotated to a corresponding potion that the shaft 231 is constrained by one of the circular profiles of the curved track of the cam 134. At this time the computer 901 sends signals to the motor 92B to control the rotation of the motor 92B. Thus, the rotation of the first support component 226 around the axis of the shaft 162 may be braked by the motion mechanism 104.

It should be noted that the above discussed cooking container unloading mechanism in the cooking apparatus 120 may be substituted by an unloading mechanism comprising: the shaft 162 which is rigidly connected with the first support component 226; the concentric bearing housings 228 a and 228 b which are rigidly connected with the second support component 175; bearings (and accessories) configured to connect the shaft 162 and the bearing housings 228 a and 228 b; a motor comprising a base component and a shaft wherein the base component is fixedly connected with the second support component 175, and whose shaft is connected to the shaft 162 by a coupling, so that a rotation of the shaft of the said motor induces a simultaneous rotation of the shaft 162. The said motor is configured to drive a rotation of the shaft 162 between a first and a second end position relative to the second support component 175, and hence the first support component 226 is rotated between the first and the second end position relative to the second support component 175. Furthermore, the motor may comprise a built-in braking mechanism configured to brake the rotation of the shaft of the motor, and hence the rotation of the shaft 162 is braked or stopped when the first support component 226 is at the first end position, and when the stirring motion mechanism in the sub-apparatus 110 is producing a motion in the cooking container 100. The motor may be a DC motor, in which case the braking mechanism of the motor may comprise the electric braking of the following types: rheostatic or dynamic braking; plugging or reverse current braking; regenerative braking, etc.

Alternatively, any of the above discussed braking mechanisms of the cooking apparatus 120 may be substituted by a mechanism comprising a C-face power-off brake, or C-face power-off brake with heavy duty enclosures, or double C-face power-off brakes, pneumatic or hydraulic brakes, shaft mounted brake, tooth brake, trailer brake, clutch brake, centrifugal brake, or caliper brake, etc. Any known braking technique may be used here to substitute the braking mechanism in the cooking apparatus 120.

Referring to FIGS. 5A-5B, a food container 182 in the shape of a bowl is configured to contain a cooked food. The interior surface of the food container 182 comprises an interior flat bottom surface 182 a in the shape of a circle, a side surface 182 c of conical shape, and a smooth surface 182 b between the flat bottom 182 a and the side surface 182 c. The smooth surface 182 b may be a part of a toroidal surface. The exterior surface of the food container 182 comprises a cylindrical surface 182 e, a planar ring 182 f, a side surface 182 g of conical shape, a ring-shaped surface 182 h, and an exterior bottom surface 182 i. The bottom surface 182 i has a flat part in the shape of a circle. The axes of the conical surfaces 182 c and 182 g, and the axis of the cylindrical surface 182 e are configured to coincide with each other. The axis of the conical surface 182 c (or 182 g) is called the axis of the food container 182. The bottom surfaces 182 a and 182 i are configured to be perpendicular to the axis of the food container 182. The food container 182 is said to be positioned upright, if the axis of the food container 182 is positioned vertically, and the exterior bottom surface 182 i is lower than the interior bottom surface 182 a. The food container 182 is configured to hold a cooked food when the food container 182 is positioned upright. The lowest point of the food container 182, when positioned upright, lies in the ring-shaped surface 182 h.

Although this is not a strict requirement, the food container 182 may be configured to be rotationally symmetric around the axis of the food container 182.

Referring to FIGS. 5C-5F, a receiving apparatus 310 comprises a plurality of food containers 182, a turntable 183, a funnel 181, a water passage 184 configured to pass waste water and a support component 186. The water passage 184 is rigidly connected to the turntable 183. The support component 186 is configured to reinforce the rigidity of the funnel 181. The receiving apparatus 310 also comprises a cyclic transport mechanism 107; wherein the cyclic transport mechanism 107 comprises a Geneva drive mechanism 106, a support component 185 and a motor 92C comprising a base component and a shaft, wherein the Geneva drive mechanism 106 drives an intermittent rotation of the turntable 183; wherein the motion of the driving wheel of the Genera mechanism 106 is produced by the motor 92C. The driven wheel of the Geneva drive mechanism comprises a cam 1061 which is configured to be rigidly connected with the turntable 183 (see FIG. 5D). The support component 186 may be rigidly connected to the support component 185 of the cyclic transport mechanism 107 (but the connection is not shown in figures) (see FIGS. 5D-5F). Both the driving wheel and driven wheel of the Geneva drive mechanism 106 of the cyclic transport mechanism 107 are constrained to rotate relative to the support component 185, wherein the axes of the rotations are configured to be vertical. Thus, the turntable 183 is rotatable around a vertical axis relative to the support component 185. As the motor 92C rotates one round (360 degrees), the turntable 183 are rotated synchronously by a fixed angle. This may be called a period of the intermittent motion.

The receiving apparatus 310 further comprises a plurality of container holders 188 each comprising: a horizontal board 188 a in the shape of a circle, a ring 188 b with a vertical axis, and a plurality of connectors 188 c configured to rigidly connect the ring 188 b and the horizontal board 188 a (also see FIG. 5C). The container holders 188 are configured to be rigidly attached to the top of the turntable 183. A food container 182 in the upright position may be placed on a container holder 188, so that the bottom of the food container 182 may touch the horizontal board 188 a, and the exterior surface 182 g of the food container 182 may be (touched and/or) restrained by the ring 188 b of the container holder 188. The container holders 188 and the water passage 184 may be cyclically moved in an intermittent rotation with the turntable 183 by the cyclic transport mechanism 107 which is driven by the motor 92C.

The receiving apparatus 310 also comprises a proximity switch 91D which is fixedly connected to the support component 185 via a connector, and a target 187 which is rigidly connected to a crank of the Geneva mechanism 106 of the cyclic transport mechanism 107. As shown in FIG. 5D, the motor 92C of the cyclic transport mechanism 107 is connected to the computer 901 via wires 94C. The computer 901 may be configured to dynamically control the timing and/or speed of the motor 92C. The proximity switches 91D are also connected to the computer 901 via wires 93D, so the computer 901 may receive electric or electronic signals from the proximity switch 91D. The proximity switch 91D senses the target 187 when the target is rotated with the crank of the Geneva mechanism 106. Each time the proximity switch 91D senses the target 187 and the electric or electronic signals of the proximity switch 91D are sent to the computer 901, the computer 901 can figure out the position of the target 187, and the position of the turntable 183. Then the computer 901 would send signals to the motor 92C as to control the rotation of the motor 92C. At each stop of the intermittent rotation, either a food container 182 or the water passage 184 may be positioned below the funnel 181.

The receiving apparatus 310 also comprises a water spray mechanism 108 comprising water pipes 311, 314, 315, 316, 317, 318, 328; connectors 312 and 313 etc. The water pipes 316, 317, 318 and 328 are configured to be fixedly attached on the inner of the funnel 181. All water pipes of the water spray mechanism 108 are configured to be connected to each other by a plurality of pipe connectors 313 and 312, so that water may flow from one pipe to another. The water spray mechanism 108 also comprises a water source 319 configured to flow water to the water pipe 311. The water source 319 may comprise a water heater connected to tap water, similar as a typical home water heater. Each of the water pipes 316, 317, 318 and 328 of the water spray mechanism 108 comprises a plurality of small holes or water outlets into spray devices (not shown in figures) so that water may be sprayed out from the small holes and/or spray devices, as to clean the inner surface of the funnel 181. When the turntable 183 is stopped at the position when the water passage 184 is below the funnel 181, the water passage 184 is configured to receive waste water which may flow from the interior of the funnel 181, such as water from the said small holes and/or the spray devices. When the turntable 183 is stopped at any other position, a cooked food may be dropped from the interior of the funnel 181 into a food container 182 on a corresponding container holder 188. It should be noted that the water passage 184 is not rigidly connected to the funnel 181, as the funnel 181 is configured to be fixed relative to the support component 185, while the turntable 183 can be rotated.

It should be noted that a spray device discussed above may comprise a spray head.

Referring to FIG. 6, a cooking sub-system 140 comprises the cooking apparatus 120 and the receiving apparatus 310. The support component 185 in the receiving apparatus 310 is configured to be rigidly or fixedly connected to the support component 175 of the cooking apparatus 120 (the connectors are not shown in figure). Since the first support component 226 of the cooking apparatus 120 is rotated from the first end position to the second end position, a cooked food or waste water in the cooking container 100 may be unloaded into the interior of the funnel 181, as to be dispensed into a food container 182 or respectively the water passage 184. It should be noted that waste water may be present in the cooking container 100 after a cleaning using water, as discussed below.

Referring to FIGS. 7A-7C, a braking mechanism 103 comprises: a shaft 141 and an eccentric shaft 143 which are rigidly connected to each other (see FIG. 7A); a slider 151 in the shape of a board, comprising a slotted hole 151 c and two ending parts 151 a and 151 b with rectangular cross sections (see FIG. 7B). The braking mechanism 103 further comprises: a support component 147; L-shaped rigid components 153 and 154 each of which comprises a horizontal side and a vertical side with a rectangular hole in the vertical side (see FIG. 7C). The L-shaped rigid component 153 is rigidly connected with the support component 147. The L-shaped rigid component 154 may be fixedly connected with the support component 147 by bolts and nuts (not shown in figures). The ending parts 151 a and 151 b of the slider 151 are configured to be separately inserted through the rectangular holes of the L-shaped rigid components 153 and 154, so that the slider 151 may be constrained to slide linearly relative to the support component 147, in a horizontal direction in a certain range.

The braking mechanism 103 also comprises a bearing housing 148, a motor 92D comprising a base component and a shaft, a connecting component 145 and a coupling 146. The bearing housing 148 is rigidly connected to the support component 147 wherein the axis of the bearing housing 148 is configured to be vertical. A pair of bearings (hidden in figure) are configured to connect the shaft 141 and the bearing housing 148, so that the shaft 141 is constrained to rotate relative to the bearing housing 148, around the axis of the shaft 141, and thus the eccentric shaft 143 is constrained to rotate around the axis of the shaft 141. A wheel 152 is mounted on the eccentric shaft 143 and is concentric with the shaft 143, such that the wheel 152 is constrained to rotate freely relative to the shaft 143, around the axis of the shaft 143. Furthermore, the wheel 152 is configured to be positioned in the slotted hole 151 c, so that the eccentric rotation of the eccentric shaft 143 around the axis of the shaft 141 may induce a back and forth sliding movement of the slider 151. The base component of the motor 92D is mounted on the connecting component 145, and the connecting component 145 is rigidly connected to the support component 147. The shaft of the motor 92D is connected to the shaft 141 by the coupling 146. Thus, the motor 92D may drive a rotation of the shaft 141 around the axis of the shaft 141, and hence the eccentric shaft 143 is eccentric rotated, around the axis of the shaft 141. Thus, the slider 151 is moved linearly back and forth relative to the support component 147.

The braking mechanism 103 also comprises two proximity switches 91E and 91F, a connector 191 in the shape of a board and a target 179 which is rigidly connected to the ending part 151 b of the slider 151. The proximity switches 91E and 91F are fixedly connected to the L-shaped component 154 (or equivalently, relative to the support component 147) via the connector 191. As shown in FIG. 7C, the motor 92D is connected to the computer 901 via wires 94D. The computer 901 may be configured to dynamically control the timing and/or speed of the motor 92D. The proximity switches 91E and 91F are also connected to the computer 901 separately via wires 93E and 93F, so the computer 901 may receive electric or electronic signals from the proximity switches 91E and 91F. When the slider 151 is slid to a first end position (or a second end position) wherein the proximity switch 91F (or respectively 91E) is configured to monitor the target 179, the electric or electronic signals are sent to the computer 901. The computer 901 can figure out the position of the target 179, and the position of the slider 151. Then the computer 901 may send signals to the motor 92D as to stop the rotation of the motor 92D to stop for a time period during which the braking mechanism 103 may complete a corresponding process. After this time period, the motor 92D, under the control of the computer 901, may restart again and rotate the slider 151 to the second end position or respectively the first end position

It should be noted that the axis of the shaft 141 and the axis of the shaft 143 in the braking mechanism 103 are configured to be parallel to each other. The distance between the two parallel axes may be at least half of the range of motion of the slider 151.

In some embodiments referring to FIGS. 8A-8B, a motion mechanism 210 comprises: a support component 266 comprising vertical boards 264, 265, 263 and a horizontal board 267; two shafts 262 and 268. The vertical board 263 and the horizontal board 267 are configured to rigidly connect the vertical boards 264 and 265. The support component 266 may be referred to as a support component of the motion mechanism 210. Each of the vertical boards 264 and 265 comprise a first bearing housing, and a second bearing housing. The axes of the first bearing housings of the vertical boards 264 and 265 are configured to be the same and the axes of the second bearing housings of the vertical boards 264 and 265 are also configured to be the same. The shaft 262 is partially round shaped and partially rectangular shaped. A bearing 269 is configured to connect (a round part of) the shaft 262 with the first bearing housing of the vertical board 264, and another bearing 269 is configured to connect (another round part of) the shaft 262 with the first bearing housing of the vertical board 265, so that the shaft 262 is constrained to rotate relative to the vertical boards 264 and 265 (or equivalently, relative to the support component 266), around the axis of the shaft 262. A bearing 279 is configured to connect the shaft 268 with the second bearing housing of the vertical board 264, and another bearing 279 is configured to connect the shaft 268 with the second bearing housing of the vertical board 265, so that the shaft 268 is constrained to rotate relative to the vertical boards 264 and 265 (or equivalently relative to the support component 266), around the axis of the shaft 268.

The motion mechanism 210 further comprises: a cam 278 comprising a curved hole; a connector 282; a shaft 283; a motor 92E comprising a shaft and a base component; a connecting component 292 configured to fixedly connect the base component of the motor 92E to the vertical board 265; and a coupling 277. The shaft 262 is configured to rigidly connected to the connector 282. The connector 282 may comprises a bearing housing (although this is not strict requirement) which is used to connect with the shaft 283 by a pair of bearings. Thus, the connector 282 and the shaft 283 are constrained to rotate relative to the support component 266 around the axis of the shaft 262 as well as the shaft 262. It should be noted that the axes of the shafts 262 and 283 are configured to be parallel to each other. The cam 278 is rigidly connected to the shaft 268 and the curved hole of the cam 278 is configured to constrain the shaft 283. The shaft of the motor 92E is joined with the shaft 268 via the coupling 277. Thus, the motor 92E may drive the rotation of the shaft 268 around the axis of the shaft 268, hence the cam 278 is rotated around the axis of the shaft 268. Since the curved hole of the cam 278 constrains the shaft 283, the rotation of the cam 278 produces a motion of the shaft 283, i.e., a rotation around the axis of the shaft 262, hence the shaft 262 is rotated around the axis of the shaft 262.

It should be noted that the curved hole in the cam 278 is modelled on a “modeling curve” comprised of a union of a middle curve and two ending curves, wherein the ending curves are arcs of two circles centered at the axis of the shaft 268. The shaft 283 (as a wheel) is constrained by the edges in the curved hole in the cam 278, by touching between the shaft 283 and the edges in the curved hole. When the shaft 283 touches the part of the edges corresponding to the ending curves, the shaft 283 may be static when the cam 278 is rotated. The modeling curve is configured to have continuously varying tangents (i.e. no sharp turns on the curve); and a smooth rotation of the cam 278 produces a motion in the shaft 283 with limited acceleration.

The motion mechanism 210 also comprises a proximity switch 91G; a connecting component 252 configured to fixedly connect the proximity switch 91G to the vertical board 265 of the support component 266; and two targets 251 a and 251 b both of which are joined with the cam 278. As shown in FIGS. 8A-8B, the motor 92E is connected to the computer 901 via wires 94E. The computer 901 may be configured to dynamically control the timing and/or speed of the motor 92E. As shown in FIG. 8A, the proximity switch 91G is also connected to the computer 901 via wires 93G, so the computer 901 may receive electric or electronic signals from the proximity switch 91G. The proximity switch 91G monitors the targets 251 a and 251 b when the targets are rotated with the cam 278. When the cam 278 is rotated to a first position (or second position) where the proximity switch 91G senses the target 251 a (or respectively 251 b), the electric or electronic signals are sent to the computer 901, the computer 901 can figure out the position of the target, and the position of the cam 278. Then the computer 901 may send signals to the motor 92E as to stop the rotation of the motor 92E for a time period during which the motion mechanism 210 can complete a corresponding process. After this time period, the motor 92E, under the control of the computer 901, may restart again and rotate the cam 278 to the second position or respectively the first position

It should be noted that the width of the curved hole in the cam 278 may be configured to be equal to or slightly larger than the diameter of the shaft 283.

Referring to FIGS. 8C-8D, a cleaning sub-apparatus 301 comprises: a rigid component 336; a cover 325 comprising a round hole at center; a connector 347 in the shape of a board; a bearing housing 346 rigidly connected to the connector 347; a shaft 338; a rigid component 343 in the shape of a board; and a C-face component 342. Both of the rigid component 343 and the C-face component 342 are configured to rigidly connect to the rigid component 336. The connector 347 is configured to rigidly connect the cover 325 to the rigid component 336 and the axis of the cover 325 is concentric with the axis of the bearing housing 346. The shaft 338 is configured to insert through of the round hole of the cover 325 and connect with the bearing housing 346 via a pair of bearings (hide in figures), so that the shaft 338 is constrained to rotate relative to the bearing housing 346 (or equivalently relative to the rigid component 336), around the axis of the shaft 338. The cleaning sub-apparatus 301 further comprises: a waterproof component 321 in the shape of a board wherein the waterproof component 321 comprises a plurality of holes; a motor 92F comprising a shaft and a base component; a connecting component 334 and a coupling 335. The waterproof component 321 is rigidly connected with the shaft 338 so that the waterproof component 321 is constrained to rotate relative to the rigid component 336 around the axis of the shaft 338 as well as the shaft 338. It should be noted that waterproof component 321 are configured to be cyclically symmetric under the rotation of 180 degrees around the central axis of the shaft 338. The base component of the motor 92F is fixedly connected to the flange of the bearing housing 346 via the connecting component 334 and the shaft of the motor 92F is joined with the shaft 338 by the coupling 335. Thus, the motor 92F may drive a rotation of the shaft 338 relative to the rigid component 336 around the axis of the shaft 338, hence the waterproof component 321 is rotated relative to the rigid component 336 around the axis of the shaft 338. It should be noted that the rigid component 336 may be referred to as the support component of the cleaning sub-apparatus 301.

It should be noted that the motor 92E is connected by wires 94E to the computer 901, so that the computer 901 may control the timing and speed of the rotation of the motor 92E.

The cleaning sub-apparatus 301 also comprises: water pipes 337 and 348; connecting components 326 and 327 both of which are configured to rigidly connect to the rigid component 336; seals 322, 323 and 324 which may be made of an elastic material, such as rubber or silica gel; and a check valve 349. The water pipes 337 and 348 are connected to each other by the check valve 349 and the water pipe 337 is inserted through the cover 325 with an outlet next to the cover 325, wherein the check valve 349 is configured to allow the water to flow from the pipe 348 to the pipe 337 and limit the water flowing from the pipe 337 to the pipe 348. A plurality of connectors 341 are configured to fixedly connect the pipes to the connecting components 326 and 327. Thus, the pipes 337 and 348 are fixed relative to the rigid component 336. The seals 322 and 323 are used to separately seal the space between the shaft 338 and the cover 325 and the space between the water pipe 337 and the cover 325, as to limit the water flow through the said spaces. The seal 324 in the shape of a ring is attached on the cover 325, wherein the external diameter of the seal 324 is equal to that of the cover 325, wherein the axis of the seal 324 is concentric with the cover 325.

Referring to FIG. 8E, a cleaning apparatus 330 comprises the braking mechanism 103, the motion mechanism 210 and the cleaning sub-apparatus 301. The vertical boards 264 and 265 of the support component 266 of the motion mechanism 210 are configured to be rigidly connected to the support component 147 of the braking mechanism 103. The shaft 262 of the motion mechanism 210 is configured to be rigidly connected to the C-face component 342 of the cleaning sub-mechanism 301, with the rectangular part of the shaft 262 inserted in the groove of the C-face component 342. Thus, the motion mechanism 210 may drive a rotation of the rigid component 336 of the cleaning sub-apparatus 301 relative to the support component 266 of the motion mechanism 210, around the axis of the shaft 262. When the rigid component 336 is rotated to the position when the rigid component 343 of the cleaning sub-apparatus 301 touches the top edge of the vertical board 263 of the motion mechanism 210, the rigid component 336 is stopped from rotating and the vertical board 263 functions as a physical barrier for the motion of the rigid component 336; wherein the position will be called the first end position of the rigid component 336 relative to the support component 266. In fact, the rotation of the rigid component 336 may also be braked by the motion mechanism 210 at both end positions. As explained, the curve profile of the curved track of the cam 278 comprises a circular arc at either end; wherein each circular arc is part of a circle centered at the axis of the shaft 268. When the shaft 283 is constrained by the curved track in the part corresponding to one of the circular arcs, the rigid component 336 and the shaft 268 may be rotated to the first end position. When the shaft 283 is constrained by the curved track in the part corresponding to the other circular arcs, the rigid component 336 and the shaft 268 may be rotated to the other end position. During the said two situations, the axis of the shaft 283 is not moved even if the cam 278 is rotated around the axis of the shaft 268. The cam 278 may then be used as a braking device for the motion of the axis of the shaft 283 around the axis of the shaft 268, under the condition that the cam 278 is not forcefully moved by the motor 92E from a still position. In fact, the axis of the shaft 283 does not move, even if the cam 278 is slightly moved; the ratio of the speed of the rotational motion of the axis of the shaft 283 and the speed of the rotational motion of the cam 278 is zero, or equivalently, the ratio of the speed of the rotational motion of the cam 278 and the speed of the rotational motion of the axis of the shaft 283 is infinity. If the axis of the shaft 283 is not moved, then the rigid component 336 cannot be rotated around the axis of the shaft 262, if not counting vibrations, errors or allowances.

The cleaning apparatus 330 also comprises a water pipe 345 which is attached on the vertical board 264 by some connectors 341. The water pipes 345 and 348 are connected to each other so that water may flow from one to the other. The water pipe 345 may be connected to a water source with a shut-off valve, and so that water may pass from the water source to the outlet next to the cover 325. The water source may comprise a water heater connected to tap water.

It should be noted that the motor 92E may or may not have a brake.

It should be noted that the angle of rotation of the rigid component 336 from the first end position to the second end position is a constant (often configured to be between 80 degrees to 120 degrees).

It should be noted that when the proximity switch 91G senses the target 251 a or 251 b, the rigid component 336 is rotated to the first end position or second end position and the shaft 283 is constrained by one of the circular profiles of the curved track of the cam 278. At this time the computer 901 would send signals to the motor 92E as control the rotation of the motor 92E according to the electric or electronic signals of the proximity switch 91G. Thus, the rotation of the rigid component 336 around the axis of the shaft 262 may be braked by the motion mechanism 210.

It should be noted that the support component 147 may be referred to as the support component of the cleaning apparatus 330.

It should be noted that the shut-off valve in the cleaning apparatus 330 may also be controlled by the computer 901.

The rigid component 336 will be referred to as a first support component of the cleaning apparatus 330. The support component 147 will be referred to as a second support component of the cleaning apparatus 330.

It should be noted that the cleaning apparatus 330 comprises the following:

(1) the cleaning device comprising waterproof component 321, the shaft 338, wherein the waterproof component 321 is rigidly connected to the shaft 338;

(2) a cleaning motion mechanism referred to as the first motion mechanism configured to produce a rotation of the cleaning device relative to the first support component 336, the cleaning motion mechanism comprising the motor 92F, the connecting component 334, the coupling 335, the bearing housing 346 and their connections to other components;

(3) a back-and-forth motion mechanism referred to as the second motion mechanism, configured to produce a rotation of the first support component 336 relative to the second support component 147 between the first end position and the second end position, wherein the back-and-forth motion mechanism comprises the motion mechanism 210 and the fixed or rigid connection between the shaft 262 and the first support component 336;

Referring to FIGS. 8F-8G, a cleaning sub-apparatus 301 a is similarly constructed as the cleaning sub-apparatus 301. Indeed, the cleaning sub-apparatus 301 a comprises the rigid component 336, the cover 331 comprising a round hole at center, the connector 347, the bearing housing 346, the shaft 338, the waterproof component 321, the rigid component 343, the C-face component 342, a motor 92G, the connecting component 334, the coupling 335, and their mutual connections (as in the cleaning sub-apparatus 301), if any. The cleaning sub-apparatus 301 a also comprises cleaning sponges 332 which are fixed to the waterproof component 321. As the motor 92G rotates, the waterproof component 321 and cleaning sponges 332 also rotate relative to the bearing housing 346 (or equivalently, relative to the rigid component 336) around the axis of the shaft 338. It should be noted that the motor 92G is connected to the computer 901, so that the computer 901 may control the timing and speed of the rotation of the motor 92G.

The cleaning sub-apparatus 301 a also comprises the water pipe 337 a, connecting components 326 and 327, a plurality of connectors 341. Similarly, as the cleaning sub-apparatus 301, the connecting components 326 and 327, and the connectors 341 are configured to fix the pipe 337 a relative to the rigid component 336, and the pipe 337 a is inserted through the cover 331 with an outlet next to the cover.

It should be noted that the waterproof component 321 may be made from plastic or metal or alloy. It can be made from one material and coated with waterproof material such as Teflon.

Referring to FIG. 8H, a cleaning apparatus 330 a is constructed the same way as the cleaning apparatus 330 except that the cleaning sub-apparatus 301 is substituted by the cleaning sub-apparatus 301 a. Indeed, the cleaning apparatus 330 a comprises the braking mechanism 103, the motion mechanism 210 and the cleaning sub-apparatus 301 a and their mutual connections (as in the cleaning apparatus 330). The vertical boards 264 and 265 of the support component 266 of the motion mechanism 210 are configured to fixedly or rigidly connect to the support component 147 of the braking mechanism 103. The shaft 262 of the motion mechanism 210 is configured to be rigidly connected to the C-face component 342 of the cleaning sub-mechanism 301 a, with the rectangular part of the shaft 262 inserted in the groove of the C-face component 342. Thus, the motion mechanism 210 may drive a rotation of the rigid component 336 relative to the support component 266 of the motion mechanism 210 around the axis of the shaft 262.

The rigid component 336 will be referred to as a first support component of the cleaning apparatus 330 a. The support component 147 will be referred to as a second support component of the cleaning apparatus 330 a.

It should be noted that the cleaning apparatus 330 a comprises the following:

(1) the cleaning device comprising the waterproof component 321, the shaft 338, wherein the waterproof component 321 is rigidly connected to the shaft 338;

(2) a cleaning motion mechanism referred to as the first motion mechanism configured to produce a rotation of the waterproof component 321 relative to the first support component 336, the cleaning motion mechanism comprising the motor 92F, the connecting component 334, the coupling 335, the bearing housing 346 and their connections to other components;

(3) a back-and-forth motion mechanism referred to as the second motion mechanism, configured to produce a rotation of the first support component 336 relative to the second support component 147 between the first end position and the second end position, wherein the back-and-forth motion mechanism comprises the motion mechanism 210 and the fixed or rigid connection between the shaft 262 and the first support component 336;

(4) the braking mechanism 103 comprising the slider 151, bearing housing 148, L-shaped rigid components 153 and 154, support component 147, motor 92D, and their mutual connections, if any.

(5) a water dispensing mechanism comprising the water pipes 337 a and 345, a water source with a shut-off valve, and the connectors 341, wherein the water pipes are configured to connected to each other, wherein the water pipe 345 is configured to connect a water source.

Referring to FIGS. 9A-9B, a cooking sub-system 150 comprises the cooking sub-system 140 and the cleaning apparatus 330. The support component 147 of the braking mechanism 103 of the cleaning apparatus 330 is configured to be rigidly or fixedly connected to the second support component 175 of the cooking sub-system 140 (the connector is not shown in figure, but can be easily done; for example, both support components 266 and 175 may be fixedly connected to the ground).

As it shows in FIG. 9B, when the first support component 226 of the cooking sub-apparatus 110 is at the first end position, the part 151 a of the slider 151 in the braking mechanism 103 may be sled as to a position where the proximity switch 91F senses the target 179 and where as to touch and press on the upper surface of the rigid component 226 b of the first support component 226. At the same time, the lower surface of rigid component 226 b of the first support component 226 is configured to be touched and pressed on from below by the L-shaped rigid component 153. Thus, the rigid component 226 b is limited by the components 151 a and 153; and the first support component 226 of the cooking sub-apparatus 110 is braked by the braking mechanism 103 of the cleaning apparatus 330 from rotating around the axis of the shaft 162.

When the support component 226, at the first end position, is braked by the braking mechanism 103, the cooking container 100 may be able to hold food or food ingredients for cooking and the stirring motion mechanism may be able to produce a motion in the cooking container 100 as to stir, mix or distribute the food or food ingredients contained in the cooking container 100. When a cooked food is completed, the part 151 a of the slider 151 of the braking mechanism 103 may be sled backward to another position where the proximity switch 91E senses the target 179, and the rigid component 226 b of the first support component 226 of the cooking sub-apparatus 110 may be rotated in the upward direction, around the axis of the shaft 162, and thus the first support component 226 and the cooking container 100 may be rotated by the motion mechanism 104 as to dispense the cooked food from the cooking container 100.

The cleaning apparatus 330 may clean the cooking container 100 when the cover 325 and the rigid component 336 are rotated to the first end position, right above the cooking container 100, and when the first support component 226 of the cooking apparatus 120 is rotated to the first end position relative to the second support component 175, and when the cooking container 100 is moved to a certain fixed position by the stirring motion mechanism of the cooking sub-apparatus 110 of the cooking sub-system 150.

The cleaning apparatus 330 of the cooking sub-system 150 may clean the cooking container 100 in six steps, as follows.

Step 1, the mechanized mechanism in the cooking container unloading mechanism in the cooking apparatus 120 (which is part of the cooking sub-system 150) moves the first support component 226 to the first end position relative to the second support component 175, so that the cooking container 100 is positioned upright.

Step 2, the shaft 262 and the first support component 336 of the cleaning apparatus 330 are simultaneously rotated to and braked at the first end position relative to the second support component 147 of the cleaning apparatus 330, and the cooking container 100 is moved by the stirring motion mechanism to a certain position. The seal 324 of the cleaning apparatus 330 is configured to press on the top edge of the cooking container 100, so that the water in the cooking container 100 could not flow through the space between the top edge of the cooking container 100 and the cover 325. It should be noted that the cooking container 100 in the above position should be best rotationally symmetric around the axis of the shaft 338.

Step 3, the water pipe mechanism of the cleaning apparatus 330 flows clean water (often heated) into the cooking container 100 from a water source with a shut-off valve.

Step 4, the cleaning device (comprising the waterproof component 321) of the cleaning apparatus 330 are high speed rotated by the cleaning motion mechanism of the cleaning apparatus 330, around the axis of the shaft 338, as to stir the water in the cooking container 100 to wash the inner surface of the cooking container 100. During this step, the water could not flow to the outside of the cooking container 100 under the sealing of the seals 322, 323 and 324.

Step 5, the shaft 262, together with the first support component 336, are rotated to the second end position and be braked.

Step 6, the motion mechanism in the cooking container unloading mechanism of the cooking apparatus 120 moves the first support component 226 to the second end position relative to the second support component 175, so that the axis of the cooking container 100 is turned, and the waste water in the cooking container 100 may be unloaded into the interior of the funnel 181 of the receiving apparatus 310 as explained before.

It should be noted that the cleaning apparatus 330 of the cooking sub-system 150 may be substituted by the cleaning apparatus 330 a. During a cleaning process, the cover 331 of the cleaning apparatus 330 a may be configured to close on the cooking container 100, and the sponges 332 of the cleaning apparatus 330 a may be configured to touch or press on the inner surface of the cooking container 100. The cleaning device (comprising waterproof component 321, the attached sponges 332, etc.) of the cleaning apparatus 330 a are low-speed rotated by the cleaning motion mechanism of the cleaning apparatus 330 a, around the axis of the shaft 338 and the sponges 332 may rub the inner surface of the cooking container 100.

Referring to FIG. 10A, a braking apparatus 103 a is constructed the same way as the braking apparatus 103 except that the support component 147 and the L-shaped rigid component 154 are substituted by the support component 147 a and the L-shaped rigid component 154 a which may have a different size or shape. Indeed, the braking apparatus 103 a comprises the support component 147 a, L-shaped rigid components 153 and 154 a, the slider 151, the shaft 141 and the eccentric shaft 143 which are rigidly connected to each other, the bearing housing 148, a motor 92H, proximity switches 91J and 91H, the connecting component 145, the connector 191 and coupling 146, and their mutual connections (as in the braking apparatus 103), if any. The support component 147 a may be referred to as the base support component of the braking apparatus 103 a. When the motor 92H rotates, slider 151 may make a back-and-forth motion in a horizontal direction relative to the support component 147 a (as in the braking apparatus 103).

As shown in FIG. 10A, the motor 92H is connected to the computer 901 via wires 94H. The computer 901 may be configured to dynamically control the timing and/or speed of the motor 92H. The proximity switches 91H and 91J are also connected to the computer 901 separately via wires 93H and 93J, so the computer 901 may receive electric or electronic signals from the proximity switches 91H and 91J. When the slider 151 is slid to a first end position (or a second end position) wherein the proximity switches 91J (or respectively 91H) is configured to sense the target 179, the computer 901 may send signals to the motor 92H as to stop the rotation of the motor 92H for a time period during which the braking mechanism 103 a may complete a corresponding process (as in the braking apparatus 103). After this time period, the motor 92H, under the control of the computer 901, may restart again and rotate the slider 151 to the second end position or respectively the first end position.

Referring to FIG. 10B-10C, a lid motion apparatus 340 comprises: a support component 385 comprising: two vertical boards 384 a, 384 b, a horizontal board 364 and a rigid component 365; shafts 383 x and 383 y; a first motion mechanism 390 a and a second motion mechanism 390 b; wherein the vertical board 384 a or 384 b of the support component 385 comprises four round holes used as four bearing housings. The horizontal board 364 and rigid component 365 are configured to rigidly connect the vertical boards 384 a and 384 b. The support component 385 may be referred to as the support component of the lid motion apparatus 340. Each of the shafts 383 x and 383 is connected with one of the four bearing housings of each of the vertical board 384 a and 384 b by bearings and accessories, so that the shaft is constrained to rotate relative to the vertical boards 384 a and 384 b, around the axis of the shaft. Each of the shafts 363 a and 363 b is connected to one of the four bearing housings of each of the vertical boards 384 a and 384 b by bearings and accessories, so that the shaft is constrained to rotate relative to the vertical boards 384 a and 384 b, around the axis of the shaft. It should be noted that each of the shafts 383 x and 383 y is partially round shaped and partially rectangular shaped.

The first motion mechanism 390 a of the lid motion apparatus 340 comprises: a shaft 363 a; a cam 386 a comprising a curved hole; a connector 361 a; a shaft 382 a; a motor 92J comprising a shaft and a base component; a coupling 391 a and a connecting component 389 a. The shafts 363 a is connected with one of the four bearing housings of each of the vertical boards 384 a and 384 b by bearings and accessories, so that the shaft 363 a is constrained to rotate relative to the vertical boards 384 a and 384 b, around the axis of the shaft 363 a. The shaft 383 x is configured to fixedly or rigidly connected to the connector 361 a and the connector 361 a may comprises a bearing housing (although this is not strict requirement) which is used to connect with the shaft 382 a by a pair of bearings. Thus, the connector 361 a and the shaft 382 a are constrained to rotate relative to the support component 385 around the axis of the shaft 383 x. In the first motion mechanism 390 a, the cam 386 a is rigidly connected to the shaft 363 a and the curved hole of the cam 386 a is configured to constrain the shaft 382 a. The base component of the motor 92J of the first motion mechanism 390 a is fixedly connected to the vertical board 384 a via the connecting component 389 a, and the shaft of the motor 92J is fixedly joined with the round part of the shaft 363 a, so that the motor 92J may produce a rotation of the shaft 363 a relative to the support component 385, hence the cam 386 a is rotated around the axis of the shaft 363 a. Since the curved hole of the cam 386 a constrains the shaft 382 a, the rotation of the cam 386 a produces a motion of the shaft 382 a, i.e., a rotation around the axis of the shaft 383 x, hence the shaft 383 x is rotated around the axis of the shaft 383 x.

The second motion mechanism 390 b of the lid motion apparatus 340 is configured the same way as the first motion mechanism 390 a. The second motion mechanism 390 b comprises: a shaft 363 b; a cam 386 b comprising a curved hole; a connector 361 b; a shaft 382 b; a motor 92K comprising a shaft and a base component; a coupling 391 b and a connecting component 389 b. The shafts 363 b is connected with one of the four bearing housings of each of the vertical boards 384 a and 384 b by bearings and accessories, so that the shaft 363 b is constrained to rotate relative to the vertical boards 384 a and 384 b, around the axis of the shaft 363 b. The shaft 383 y is configured to fixedly or rigidly connected to the connector 361 b and the connector 361 b may comprises a bearing housing (although this is not strict requirement) which is used to connect with the shaft 382 b by a pair of bearings. Thus, the connector 361 b and the shaft 382 b are constrained to rotate relative to the support component 385 around the axis of the shaft 383 y. In the second motion mechanism 390 b, the cam 386 b is rigidly connected to the shaft 363 b and the curved hole of the cam 386 b is configured to constrain the shaft 382 b. The base component of the motor 92K of the second motion mechanism 390 b is fixedly connected to the vertical board 384 b via the connecting component 389 b and the shaft of the motor 92K is fixedly joined with the round part of the shaft 363 b, so that the motor 92K may drive a rotation of the shaft 363 b relative to the support component 385, hence the cam 386 b is rotated around the axis of the shaft 363 b. Since the curved hole of the cam 386 b constrains the shaft 382 b, the rotation of the cam 386 b produces a motion of the shaft 382 b, i.e. a rotation around the axis of the shaft 383 y, hence the shaft 383 y is rotated around the axis of the shaft 383 y.

It should be noted that the curved hole in the cam 386 a (or 386 b) of the first motion mechanism 390 a (or respectively the second motion mechanism 390 b) is modelled on a “modeling curve” comprised of a union of a middle curve and two ending curves, wherein the ending curves are arcs of two circles centered at the axis of the shaft 363 a (or respectively 363 b). The shaft 382 a (or 382 b) of the first motion mechanism 390 a (or respectively the second motion mechanism 390 b) can be regarded as a wheel. The shaft 382 a (or 382 b) is constrained by the edges in the curved hole in the cam 386 a (or respectively 386 b) of the first motion mechanism 390 a (or respectively the second motion mechanism 390 b), when the shaft 382 a (or 382 b) and the edges in the curved hole are mutually touched. When the shaft 382 a (or 382 b) of the first motion mechanism 390 a (or respectively the second motion mechanism 390 b) touches the parts of the edges corresponding to the ending curves, the shaft 382 a (or 382 b) may be static when the cam 386 a (or 386 b) is rotated. The modeling curve is configured to have continuously varying tangents (i.e. no sharp turns on the curve); and a smooth rotation of the cam 386 a (or 386 b) of the first motion mechanism 390 a (or respectively the second motion mechanism 390 b) produces a motion in the shaft 382 a (or respectively 382 b) with finite acceleration.

The lid motion apparatus 340 also comprises a rigid component 388 rigidly connected to the vertical board 384 a; some pipe fixing components 366 which are rigidly or fixedly connected to the vertical boards 384 a and 384 b.

The lid motion apparatus 340 also comprises proximity switches 91K and 91L; connecting components 394 a and 394 b configured to separately fixedly connect the proximity switches 91K and 91L to the vertical boards 384 a and respectively 384 b; targets 392 a and 393 a both of which are joined with the cam 386 a; targets 392 b and 393 b both of which are joined with the cam 386 b. As shown in FIGS. 10B-10C, the motors 92K and 92J are connected to the computer 901 separately via wires 94K and 94J. The computer 901 may be configured to dynamically control the timing and/or speed of the motor 92J of the first motion mechanism 390 a, and those of the motor 92K of the second motion mechanism 390 b. The proximity switches 91K and 91L are also connected to the computer 901 separately via wires 93K and 93L, so the computer 901 may receive electric or electronic signals from the proximity switches 91K and 91L. The proximity switch 91K monitors the target 392 a when the target is rotated in one direction with the cam 386 a of the first motion mechanism 390 a by the motor 92J. The proximity switch 91K monitors the target 393 a when the target is rotated in the other direction with the cam 386 a of the first motion mechanism 390 a by the motor 92J. Each time the proximity switch 91K senses the target 392 a or 393 a, the computer 901 can figure out the position of the target, and the position of the cam 386 a. Then the computer 901 may receive signals from the proximity switch 91K, and then send signals to the motor 92J as to stop the rotation of the motor 92J for a time period. After this time period, the motor 92J, under the control of the computer 901, may restart again and make a reverse rotation to rotate the cam 386 a to the next position. Similarly, the proximity switch 91L senses the target 392 b when the target is rotated in one direction with the cam 386 b of the second motion mechanism 390 b by the motor 92K. The proximity switch 91L senses the target 393 b when the target is rotated in the other direction with the cam 386 b of the second motion mechanism 390 b by the motor 92K. Each time the proximity switch 91L senses the target 392 b or 393 b, the computer 901 can figure out the position of the target, and the position of the cam 386 b. Then the computer 901 may receive signals from the proximity switch 91L, and then send signals to the motor 92K as to stop the rotation of the motor 92K for a time period. After this time period, the motor 92K, under the control of the computer 901, may restart again and make a reverse rotation to rotate the cam 386 b to the next position.

It should be noted that the width of the curved hole in the cam 386 a (or 386 b) may be configured to be equal to or slightly larger than the diameter of the shaft 382 a (or respectively 382 b).

Referring to FIGS. 10D-10H a lid apparatus 350 (similar to the “lid apparatus 301” of the U.S. patent application Ser. No. 14/918,608, Filed Oct. 31, 2015) comprises: a blocking device 371 comprising a ring shaped component 372 and a flat ring-shaped board which are rigidly connected to each other; a solid cover 373; the braking apparatus 103 a and the lid motion apparatus 340, wherein the support component 147 a of the braking apparatus 103 a is configured to rigidly connected to the support component 385 of the lid motion apparatus 340, wherein the support component 147 a may be referred to as the support component of the lid apparatus 350. The solid cover 373 is rigidly connected to the shaft 383 y by the connector 378 (see FIG. 10D); and the blocking device 371 is rigidly connected to the shaft 383 x by the connector 379 (see FIG. 10E). The axes of the shafts 383 x and 383 y in the lid motion apparatus 340 are configured to be horizontal. The blocking device 371 is configured to be rotated by the first motion mechanism 390 a to a position where the connector 379 touches the component 388 of the lid motion apparatus 340, wherein the component 388 functions as a physical barrier for the motion of the connector 379. The position of the blocking device 371 at this time will be referred to as the first end position of the blocking device 371 relative to the support component 385. When the blocking device 371 is at the first end position, the solid cover 373 can be rotated by the second motion mechanism 390 b to a position where the solid cover 373 seamlessly covers the ring-shaped component 372 of the blocking device 371.

In fact, the blocking device 371 may be braked by the first motion mechanism 390 a of the lid motion apparatus 340 when the blocking device 371 is at the first end position. As explained, the curve profile of the curved track of the cam 386 a of the first motion mechanism 390 a comprises a circular arc at either end; wherein each circular arc is part of a circle centered at the axis of the shaft 363 a. When the shaft 382 a is constrained by the curved track in the part corresponding to one of the circular arcs, the blocking device 371 and the shaft 363 a may be rotated to the first end position. When the shaft 382 a is constrained by the curved track in the part corresponding to the other circular arc, the blocking device 371 and the shaft 363 a may be rotated to a second end position wherein the rotation angle of the blocking device 371 relative to the first end position is a constant (in some applications near 90 degrees). During either situation, the axis of the shaft 382 a is not moved even if the cam 386 a of the first motion mechanism 390 a is rotated around the axis of the shaft 363 a. The cam 386 a of the first motion mechanism 390 a may be used to stop the motion of the blocking device 371 relative to the support component 385 when the blocking device 371 is moved to the first position or second position relative to the support component 385 under the condition that the motor 92J of the first motion mechanism 390 a is power off. In fact, the axis of the shaft 382 a does not move, even if the cam 386 a is slightly moved; the ratio of the speed of the rotational motion of the axis of the shaft 382 a and the speed of the rotational motion of the cam 386 a is zero, or equivalently, the ratio of the speed of the rotational motion of the cam 386 a and the speed of the rotational motion of the axis of the shaft 382 a is infinite. If the axis of the shaft 382 a is not moved, then the blocking device 371 cannot be rotated around the axis of the shaft 383 x, if not counting vibrations, errors or allowances. Similarly, as the blocking apparatus 371, the cam 386 b of the second motion mechanism 390 b of the lid motion apparatus 340 may be used as a mechanism for the rotation of the solid cover 373 and the connector 378 when the solid cover 373 and the connector 378 are rotated to the first end position or a second end position. It should be noted that the motors 92J and 92K may not need to have a brake in some applications.

It should be noted that when the proximity switch 91K (or respectively 91L) senses the target 392 a or 393 a (or respectively 392 b or 393 b), the solid cover 373 (or respectively the blocking device 371) is rotated to the first end position or second end position and the shaft 383 x (or respectively 383 y) can be constrained by one of the circular profiles of the curved track of the cam 386 a (or 386 b). At this same time, the computer 901 may send signals to the motor 92J (or respectively 92K) as to control the rotation of the motor 92J (or respectively 92K). Thus, the rotation of the solid cover 373 (or respectively the blocking device 371) may be braked by the lid motion apparatus 340.

The lid apparatus 350 further comprises a liquid dispensing mechanism comprising a plurality of pipes 377, 375, pipe fixing components 374, a plurality of connectors and spray heads 376. The pipes 375 of the liquid dispensing mechanism are configured to be fixed relative to the support component 385 via the pipe fixing components 374 and 366. Each pipe 375 is configured to be connected to a corresponding pipe 377 by a connector. Each spray head 376 is installed on the ring-shaped component 372 of the blocking device 371 and is connected to a corresponding pipe 377. The liquid dispensing mechanism is configured dispense liquid ingredients, such as water, cooking oil, soy source, vinegar, etc., into the cooking container 100 in a cooking process. Each pipe 375 in the liquid dispensing mechanism of the lid apparatus 350 may be connected to a liquid source, via a pipe through a liquid pump such as peristaltic pump, wherein the said liquid pump is configured to pump the liquid in the said liquid source to the cooking container 100 via the said pipe 375. The computer may be configured to control the rotation of the said liquid pump.

When the blocking device 371 is rotated to the first end position relative to the support component 385, and when the cooking container 100 of the cooking apparatus 120 of the cooking sub-system 150 is rotated to the first end position relative to the second support component 175 of the cooking apparatus 120, the distance β between the top edge of the cooking container 100 and lower surface of the blocking device 371 is configured to be small (see FIG. 10H). The distance β is only needed to make room for elastic and other deformations, and allowances in spaces and errors. Thus, the distance β need not be more than the sum of the following quantities: (a) the maximal effect caused by the elastic or other non-rigid deformation of the cooking container 100; (b) the maximal effect caused by the elastic or other non-rigid deformation of the blocking device 371; (c) the allowances in spaces and errors. In our applications, the sum of these quantities may be configured to be less than two millimeters, and thus the distance β is configured to be less than two millimeters.

Referring to FIGS. 11A-11B, an automated cooking sub-system 160 comprises the cooking sub-system 150 and the lid apparatus 350. The support component 147 a of the lid apparatus 350 is configured to rigidly connect to the support component 175 of the cooking sub-system 150 (the rigid connection is not shown in figure, but it is elementary to construct it, e.g., by mounting the support component 385 and the second support component 175 rigidly on the ground). When the blocking device 371 is rotated to the first end position relative to the support component 385 by the motor 92J of the lid motion apparatus 340, the blocking device 371 is configured to comprise a lower surface which lies on a horizontal plane. When the blocking device 371 is rotated to the first end position relative to the support component 385, and when the cooking container 100 of the cooking apparatus 120 of the cooking sub-system 150 is rotated to the first end position relative to the second support component 175 of the cooking apparatus 120, the top edge of the cooking container 100 is configured to be on a horizontal plane which is very close to the horizontal plane containing the lower surface of the blocking device 371. The distance between the two horizontal planes is configured to be quite small, often less than a couple of millimeters, or even less than lmillimeter in some applications. The axes of the shafts 131, 132, 125 and 126 are configured to be vertical when the first support component 226 of the cooking apparatus 120 is at the first end position relative to the second support component 175 of the cooking apparatus 120. Thus, the stirring motion mechanism of the cooking sub-apparatus 110 of the cooking apparatus 120 moves the cooking container 100 by a horizontal planar motion relative to the first support component 226 when the first support component 226 is at the first end position relative to the second support component 175 of the cooking apparatus 120. If so, the edge of the cooking container 100 is contained in the same horizontal plane when the first support component 226 is at the first end position relative to the second support component 175. When the solid cover 373 is also rotated to the first end position relative to the support component 385 by the lid motion apparatus 340, the solid cover 373 and the blocking device 371 are configured to always nearly cover the cooking container 100 when the cooking container 100 is moved by the stirring motion mechanism of the cooking sub-apparatus 110. Therefore, the solid cover 373 and the blocking device 371 may help limit the food or food ingredients contained in the cooking container 100 from jumping out of the food container 100 when the stirring motion mechanism moves the cooking container 100 robustly.

As it shows in FIG. 11B, the braking mechanism 103 a is configured similarly as the braking mechanism 103. When the cooking sub-apparatus 110 is at the first end position, the proximity switch 91J is able to sense the target 179, and the part 151 a of the slider 151 in the braking mechanism 103 a may be sled as to touch and press on the upper surface of the rigid component 226 a of the first support component 226. At the same time, the lower surface of rigid component 226 a of the first support component 226 is configured to be touched and pressed on from below by the L-shaped rigid component 153. Thus, the rigid component 226 a is limited by the components 151 a and 153; and the first support component 226 of the cooking sub-apparatus 110 is braked by the braking mechanism 103 a of the lid apparatus 350 from rotating around the axis of the shaft 162.

When the first support component 226 is braked by the braking mechanism 103 a the cooking container 100 may be able to hold food or food ingredients for cooking and the stirring motion mechanism may be able to produce a motion in the cooking container 100 as to stir, mix or distribute the food or food ingredients contained in the cooking container 100. When a cooked food is produced, the part 151 a of the slider 151 of the braking mechanism 103 a may be sled backward to the position where the proximity switch 91H senses the target 179, the rigid component 226 a of the first support component 226 of the cooking sub-apparatus 110 may be free to be rotated in the upward direction, around the axis of the shaft 162, and thus the first support component 226 and the cooking container 100 may be rotated by the motion mechanism 104 as dispense the cooked food from the cooking container 100.

It should be noted that the braking mechanism 103 of the cleaning apparatus 330 and the braking mechanism 103 a of the lid apparatus 350 may be configured to work at the same time.

It should be further noted that braking mechanism 103 of the cleaning apparatus 330 and the braking mechanism 103 a of the lid apparatus 350 be used to reduce vibrations (or other non-rigid motions, errors or allowances) of the first support component 226, and to enhance the stability of the first support component 226, when the first support component 226 is at the first end position relative to the second support component 175, and when the stirring motion mechanism produces a motion of the cooking container 100 as to stir, mix or distribute the food or food ingredients held in the cooking container 100.

In the automated cooking sub-system 160, after a food in the cooking container 100 of the cooking apparatus 120 is cooked, the solid cover 373 is rotated to the second end position relative to the support component 385. Next, the blocking device 371 is rotated to the second end position, wherein the solid cover 373 is kept stayed at the second end position.

Next, the first support component 226 of the cooking apparatus 120 is rotated to the second end position relative to the second support component 175, as to dispense the cooked food into a food container 182 on the turntable 183, through the funnel 181, of the receiving apparatus 310. Next, the first support component 226 of the cooking apparatus 120 is rotated back to the first end position relative to the second support component 175 so the cooking container 100 is positioned upright. Next, the rigid component 336 of the cleaning apparatus 330 is rotated to the first end position relative to the support component 266, so that the cleaning mechanism may pour water into the cooking container 100 and clean the cooking container 100. Next, the rigid component 336 is rotated back to the second end position. Meanwhile, the turntable 183 of the receiving apparatus 310 is rotated so that the water passage 184 is positioned right below the funnel 181. Next, the first support component 226 is rotated to the second end position relative to the second support component 175, as to unload the waste water in the cooking container 100, to flow away through the funnel 181 and to the water passage 184. Then, the first support component 226 is rotated back to the first end position relative to the second support component 175; and the water may flow from the water pipes 316, 317, 318, 328, etc., as to clean the funnel 181.

The second support component 175 of the cooking apparatus 120 may be referred to as a support component of the automated cooking sub-system 160.

More lid apparatuses are presented in the U.S. patent application Ser. No. 14/918,608, Filed Oct. 31, 2015, the disclosures of which are all herein incorporated by reference in their entireties. These lid apparatuses may be combined with the cooking apparatuses and cooking sub-systems or systems presented in the present patent application.

In some embodiments, a lid apparatus may comprise a blocking device and a cover, both of which are fixedly or rigidly connected to each other, and a motion mechanism comprising a motor configured to drive a rotation of the blocking device and the cover, around a horizontal axis, between two end positions. It should be noted that a motion mechanism which drives a rotation of a blocking device in a lid apparatus may or may not comprise a modified Geneva drive mechanism. However, there needs to be a limit mechanism configured to limit the rotation of the blocking device to a fixed range between two end positions, wherein the limit mechanism may comprise physical barriers.

Referring to FIGS. 12A-12E, a gripping mechanism 401 comprises a pair of gripping devices 411 a and 411 b; a rigid component 418 referred to as the support component of the gripping mechanism 401; a pair of shafts 417 a and 417 b; two rigid components 416 a and 416 b each comprising a bearing housing (corresponding to a round hole shown in FIG. 12B); and shafts 421 and 422. As shown in FIG. 12A, the gripping device 411 a (or 411 b) comprises a bearing housing 415 a (or respectively 415 b); a gripper 412 a (or respectively 412 b) comprising a plurality of surfaces (on the gripping side) each comprising a part of a cylindrical surface; an arm 413 a (or respectively 413 b); a shaft 414 a (or respectively 414 b); wherein the arm 413 a (or respectively 413 b) is a rigid component configured to rigidly connect the gripper 412 a (or respectively 412 b), the bearing housing 415 a (or respectively 415 b) and the shaft 414 a (or respectively 414 b); wherein the axis of the bearing housing 415 a (or respectively 415 b) and the axis of the shaft 414 a (or respectively 414 b) are configured to be parallel to each other. The arm 413 a (or 413 b) may comprise stiffeners. As shown in FIG. 12B, the pair of shafts 417 a and 417 b are both rigidly connected to the rigid component 418 wherein the axes of the shafts 417 a and 417 b are configured to be parallel to each other, and perpendicular to the axes of the shafts 421 and 422. The shafts 421 and 422 are both rigidly connected to the rigid component 418 wherein the axes of the two shafts are configured to be the same. The two rigid components 416 a and 416 b are both rigidly connected to the rigid component 418. The axes of the bearing housings of the rigid components 416 a and 416 b are configured to be the same, and parallel to the axes of the shafts 421 and 422.

A pair of bearings 424 a (and accessories) are configured to connect the shaft 417 a and the bearing housing 415 a of the gripping device 411 a, so that the gripping device 411 a is constrained to rotate relative to the shaft 417 a (or equivalently, relative to the rigid component 418) around the axis of the shaft 417 a. Similarly, another pair of bearings 424 b (and accessories) are configured to connect the shaft 417 b and the bearing housing 415 b of the gripping device 411 b, so that the gripping device 411 b is constrained to rotate relative to the shaft 417 b (or equivalently, relative to the rigid component 418) around the axis of the shaft 417 b. As shown in FIGS. 12C-12D, the gripping mechanism 401 also comprises: a pair of screw nuts 427 a and 427 b; a pair of shafts 429 a and 429 b; a pair of links 428 a and 428 b; a screw shaft 426 comprising a horizontal axis; and a motor 92L comprising a base component and a shaft. The shaft 429 a (or 429 b) is rigidly joined with the screw nut 427 a (or respectively 427 b), and the axis of the shaft 429 a (or 429 b) is configured to be perpendicular to the axis of the screw nuts 427 a (or respectively 427 b). The shaft 429 a (or 429 b) is constrained to rotate relative to the link 428 a (or respectively 428 b) around the axis of the shaft 429 a (or respectively 429 b). The shaft 414 a (or 414 b) is constrained to rotate relative to the link 428 a (or respectively 428 b) around the axis of the shaft 414 a (or respectively 414 b). The axis of the shaft 414 a (or 414 b) is configured to be parallel to the axis of the shaft 429 a (or respectively 429 b). The screw shaft 426 is configured to be engaged with the screw nuts 427 a and 427 b, and the axis of the screw shaft 426 coincides with the axes of the screw nuts 427 a and 427 b. When the screw shaft 426 rotates, the screw nuts 427 a and 427 b are configured to simultaneously move in opposite directions, by the same speed. A pair of ball or roller bearings 431 are configured to connect the above discussed bearing housing of the rigid component 416 a with a smooth round section of the screw shaft 426, and another pair of ball or roller bearings 431 are configured to connect the above discussed bearing housing of the rigid component 416 b with another smooth round section of the screw shaft 426, so that the screw shaft 426 is constrained to rotate relative to the rigid components 416 a and 416 b (or equivalently, relative to the rigid component 418) around the axis of the screw shaft 426. A rotation of the screw shaft 426 may induce translations of the screw nuts 427 a and 427 b relative to the screw shaft 426, hence the shafts 429 a,429 b, 414 a and 414 b are moved relative to the support component 418. The motion of the shaft 414 a (or 414 b) induces a rotation of the gripping device 411 a (or respectively 411 b) relative to the support component 418, around the axis of the shaft 417 a (or respectively 417 b). It should be noted that the gripping devices 411 a and 411 b are rotated simultaneously in opposite directions. Since the gripping devices 411 a and 411 b are rotated, the grippers 412 a and 412 b may grip or release a container 111 which may hold food or food ingredients. The base component of the motor 92L is configured to be rigidly or fixedly connected to the rigid component 416 b, and the shaft of the motor 92L is configured to fixedly connected to and concentric with the screw shaft 426, so that the motor 92L may drive a rotation of the screw shaft 426 around the axis of the screw shaft 426. Thus, the rotation produced by the motor 92L on the screw shaft 426 may induce simultaneous rotations of the grippers 411 a and 411 b in opposite directions as to grip or release an ingredient container of various size.

The gripping mechanism 401 also comprises: two proximity switches 91N and 91M; a connector 438 configured to fixedly connect the two proximity switches 91N and 91M to the rigid component 416 a (or equivalently, to the support component 418); a board 439 comprising targets 439 a, 439 b, 439 c and 439 d. The board 439 is attached on the arm 413 a of the gripping device 411 a. As shown in FIG. 12E, the motor 92L are connected to the computer 901 via wires 94L. The computer 901 may be configured to dynamically control the timing and/or speed of the motor 92L. The proximity switches 91M and 91N are also connected to the computer 901 separately via wires 93M and 93N, so the computer 901 may receive electric or electronic signals from the proximity switches 91M and 91N. The proximity switch 91M (or 91N) monitors the targets 439 a, 439 b and 439 c (or respectively 439 d) when the targets are rotated with the pair of gripping devices 411 a and 411 b. When the proximity switch 91M senses the target 439 a and the proximity switch 91N senses the target 439 d, the gripping devices 411 a and 411 b are rotated by the motor 92L to a position as to grip a large size ingredient container. When the proximity switch 91M senses the target 439 b and the proximity switch 91N senses the target 439 d, the gripping devices 411 a and 411 b are rotated by the motor 92L to a position as to grip a middle size ingredient container. When the proximity switch 91M senses the target 439 c and the proximity switch 91N senses the target 439 d, the gripping devices 411 a and 411 b are rotated by the motor 92L to a position to grip a small size ingredient container.

FIG. 12E shows an ingredient container 111 of a large size gripped by the gripping devices 411 a and 411 b of the gripping mechanism 401.

It should be noted that the screw threads of the screw nuts 427 a and 427 b may be configured to be of opposite helical directions, while the screw shaft 426 is configured to comprise two corresponding screw threads with opposite helical directions.

Referring to FIG. 12F, a motion mechanism 402 which is similarly constructed as the motion mechanism 104 comprises: a cam 452 comprising a curved track, i.e. a curved hole of a certain width; a rigid component 451 comprising a bearing housing 451 a; a shaft 453; a coupling 447; and a motor 92M comprising a shaft and a base component. The cam 452 is fixedly connected to the shaft 453. A bearing 448 is configured to connect the shaft 453 and the bearing housing 451 a of the rigid component 451, so that the shaft 453 is constrained to rotate relative to the rigid component 451, around the axis of the shaft 453. The base component of the motor 92M is rigidly connected to the rigid component 451, and the shaft of the motor 92M is fixedly connected to the shaft 453 by the coupling 447. Thus, the motor 92M may drive the rotation of the shaft 453 relative to the rigid component 451 around the axis of the shaft 453, and hence the cam 452 is rotated relative to the rigid component 451 around the axis of the shaft 453. The curved track of the cam 452 has a curved profile comprising a circular arc at either end of the curved profile; where each circular arc is a part of a circle centered at the axis of the shaft 453. The edge of the curved track of the cam 452 comprises equidistant curve to the curved profile.

The motion mechanism 402 also comprises a proximity switch 91P fixedly connected to the bearing housing 451 a via a connector; and two targets 449 a and 449 b both of which are joined with the cam 452. As shown in FIG. 12F, the motor 92M is connected to the computer 901 via wires 94M. The computer 901 may be configured to dynamically control the timing and/or speed of the motor 92M. The proximity switch 91P is also connected to the computer 901 via wires 93P, so the computer 901 may receive electric or electronic signals from the proximity switch 91P. The proximity switch 91P monitors the target 449 a when the target is rotated in one direction with the cam 452 by the motor 92M. Similarly, the proximity switch 91P monitors the target 449 b when the target is rotated in the other direction with the cam 452 by the motor 92M. When the cam 452 is rotated to a first position (or respectively second position) the proximity switch 91P senses the target 449 a or 449 b, the electric or electronic signals are sent to the computer 901, the computer 901 can figure out the position of the target, and the position of the cam 452. Then the computer 901 may send signals to the motor 92M to stop the rotation of the motor 92M during which the motion mechanism 402 can complete a corresponding process. After this time period, the motor 92M, under the control of the computer 901, may restart again and make a reverse rotation to rotate the cam 452 to the second position or respectively the first position.

Referring to FIGS. 12G-12H, an dispensing apparatus 410 comprises: the gripping mechanism 401; the motion mechanism 402; a support component 434 referred to as the support component of the dispensing apparatus 410; a gear 436 configured to be rigidly or fixedly connected to the shaft 421 of the gripping mechanism 401; a partial gear 437 comprising a bearing housing 437 a at the center; shafts 441 and 443 whose axes are configured to be horizontal and parallel to the axis of the shaft 421; a wheel 445; and two vertical boards 433 and 435 each comprising a bearing housing, wherein the axis of the partial gear 437 is configured to be the same as the axis of the bearing housing 437 a, wherein the vertical boards 433 and 435 are rigidly connected to the support component 434, wherein the axes of the bearing housing of the two vertical boards 433 and 435 are configure to be the same as the axes of the shaft 421 and 422 of the gripping mechanism 401.

As shown in FIG. 12G, a bearing 432 is configured to connect the shaft 422 (or 421) and the bearing housing of the vertical board 433 (or respectively 435), so that the shaft 422 (or respectively 421) is constrained to rotate relative to the vertical boards 433 (or respectively 435), or equivalently, relative to the support component 434, around the axis of the shafts 421 and 422. As explained before, the shafts 421 and 422 are rigidly connected to the rigid component 418; thus, the rigid component 418 of the gripping device 401 is constrained to rotate relative to the support component 434 around the axis of the shaft 421. The shaft 441 is rigidly connected to the vertical board 435. A bearing 442 is configured to connect the shaft 441 and the bearing housing 437 a of the partial gear 437, so that the partial gear 437 is constrained to rotate relative to the shaft 441, or equivalently, relative to the support component 434, around the axis of the shaft 441. The partial gear 437 is engaged to the gear 421. The shaft 443 is rigidly connected to the partial gear 437; and the wheel 445 is concentric with the shaft 443 and is constrained to rotate relative to the shaft 443 around the axis of the shaft 443.

As shown in FIG. 12H, the wheel 445 is configured to be inserted in the curved track of the cam 452 of the motion mechanism 402, so that the edges of the curved track of the cam 452 may constrain the shaft 443. The width of the curved track of the cam 452 is nearly the same as the diameter of the wheel 445, with a very small allowance (less than 0.1 mm in some applications, although this is not a strict requirement). The rigid component 451 of the motion mechanism 402 is configured to be rigidly connected to the support component 434 (though the rigid connection is not shown in figure). The shafts 441 and 453 are configured to have parallel axes. As the cam 452 is rotated relative to the rigid component 451 by the motor 92M of the motion mechanism 402, the shaft 443 is rotated relative to the support component 434 around the axis of the shaft 441, hence the partial gear 437 is rotated around the axis of the shaft 441, and hence the support component 418 of the gripping mechanism 401, together with a gripped ingredient container if any, e.g., the ingredient container 111 as shown in FIG. 12G, are rotated around the axis of the shaft 441.

The distance between the axes of the shafts 443 and 441 is configured to be smaller than the distance between the axes of the shafts 441 and 453. The axes of the shafts 441, 443 and 453 are configured to be never collinear, and thus, the rotation of the partial gear 437 (around the shaft 441) has a limited range (less than 180 degrees). The rotation of the cam 452 (around the axis of the shaft 453) also has a limited range, as the wheel 445 restricts the rotation of the cam 452. The partial gear 437 is at an end position relative to the support component 434 if the wheel 445 is touched by the curved track corresponding to one of the circular ends. Since the gear 432 is engaged with the partial gear 437, the gear 432 and the support component 418 of the gripping mechanism 401 are rotated (around the axis of the shaft 421) between two end positions relative to the support component 434. When the support component 418 is rotated to a first end position, the axis of a gripped ingredient container (e.g., ingredient container 111), if any, is configured to be vertical and the gripped ingredient container is positioned upright. When the support component 418 of the gripping mechanism 401 is rotated from the first end position to the second end position, the gripped ingredient container, if any, is configured to be rotated by a certain degree as to dispense the food or food ingredients from the ingredient container into a cooking container 100, as shown in FIG. 12G (where the ingredient container 111 is positioned with bottom on the up side). It should be noted that the angular range of rotation of the support component 418 between the two end positions, may be configured to be a constant chosen between 120 to 180 degrees, or in a more restrictive application, between 135 degrees or 170 degrees.

It should be noted that when the proximity switch 91P senses the target 449 a or 449 b, the support component 418 of the gripping mechanism 401 is rotated to the first end position or respectively second end position and the shaft 231 is constrained by one of the circular profiles of the curved track of the cam 452. At this time the computer would send signals to the motor 92M as to control the rotation of the motor 92M. Thus, the rotation of the rigid component 418 around the axis of the shaft 421 or 422 may be braked by the motion mechanism 402 (as the 104).

It should be noted that the dispensing apparatus 410 comprises the followings:

(1) the gripping mechanism 401 configured to grip or release a container 111, wherein the gripping mechanism 401 comprises the rigid component 418, to be referred to as the support component of the gripping mechanism 401, or a first support component; a pair of gripping devices 411 a and 411 b which are configured to be constrained to rotate relative to the first support component 418; the motor 92L, proximity switches 91N and 91M; the rigid components 416 a and 416 b; the shafts 417 a and 417 b; the screw shaft 426; the screw nuts 427 a and 427 b; the shafts 429 a and 429 b; the links 428 a and 428 b; etc.; and their connections to each other if any, and their connections to the other components of the dispensing apparatus 410 if any;

(2) a rotational motion mechanism comprising the rigid component 434 referred to as the support component of the rotational motion mechanism, or a second support component, wherein the rotational motion mechanism is configured to produce an rotation of the first support component 418 between a first end position and a second end position relative to the second support component 434, around the axis of the shaft 421 (which is horizontal); wherein the rotational motion mechanism also comprises the motion mechanism 402, the gear 436, the partial gear 437 and the shaft 443, the shaft 441, the wheel 445, etc.; and their connections to each other if any, and their connections to other components of the dispensing apparatus 410 if any.

Referring to FIG. 13, a cooking sub-system 170 comprises the automated cooking sub-system 160 and the dispensing apparatus 410 wherein the support component 434 of the dispensing apparatus 410 is rigidly connected to the second support component 175 of the automated cooking sub-system 160 (though the connection is not shown in figure; it is quite elementary to build the connection). As explained before, the dispensing apparatus 410 is configured to grip and then rotate an ingredient container (of several sizes), e.g. an ingredient container 111, while rotating the support component 418 of the gripping mechanism 401 between a first end position and a second end position relative to the support component 434.

Before the start of a cooking process of a food using food ingredients from an ingredient container, the rigid component 336 of the cleaning apparatus 330 of the automated cooking sub-system 160 needs to be rotated to the second end position relative to the support component 266 of the cleaning apparatus 330, and the first support component 226 of the cooking apparatus 120 of the automated cooking sub-system 160 needs to be rotated to the first end position relative to the second support component 175 of the cooking apparatus 120. Next, the solid cover 373 of the lid apparatus 350 of the automated cooking sub-system 160 is rotated to the second end position relative to the support component 385 of the lid apparatus 350, and the blocking device 371 is rotated to the first or second end position relative to the support component 385 of the lid apparatus 350. Then, the support component 418 of the gripping mechanism 401 (of the dispensing apparatus 410) may be rotated from the first end position to the second end position relative to the support component 434 of the dispensing apparatus 410, and the gripped ingredient container, if any, is rotated together with the support component 418, and the food or food ingredients contained in the gripped ingredient container are configured to be dispensed into the cooking container 100.

Referring to FIGS. 14A-14C, a gripping mechanism 403 comprises a support component 464, referred to as the support component of the gripping mechanism 403. The gripping mechanism 403 also comprises a pair of shafts 462 a and 462 b both of which are rigidly connected to the support component 464. See FIG. 14A. The gripping mechanism 403 further comprises: a pair of shafts 463 a and 463 b; a rigid component 471 in the shape of a board; a shaft 489 which is rigidly connected to the rigid component 471 and positioned in the middle of the rigid component 471; a motor 92N comprising a shaft and a base component; and a connecting component 468. Both the shafts 463 a and 463 b are configured to be rigidly connected to the rigid component 471 and separately positioned at the both ends of the rigid component 471. A wheel 469 is mounted on the shaft 463 a and is concentric with the shaft 463 a, such that the said wheel is constrained to rotate freely relative to the shaft 463 a, around the axis of the shaft 463 a. Another wheel 469 is mounted on the shaft 463 b and is concentric with the shaft 463 b, such that the said wheel is constrained to rotate freely relative to the shaft 463 b around the axis of the shaft 463 b. The base component of the motor 92N is fixedly connected to the support component 464 by the connecting component 468, and the shaft of the motor 92N is configured to fixedly connect to the shaft 489 by a coupling 472. Thus, the motor 92N may drive a rotation of the rigid component 471 relative to the support component 464. The gripping mechanism 403 further comprises a screw nut 465 and a linear slider 466, wherein the screw nut 465 is rigidly connected to the support component 464, and the linear slider 466 is fixedly mounted on the support component 464. The axes of the shafts 462 a, 462 b, 489, 463 a and 463 b, the axis of the screw nut 465 and the linear direction of the linear slider 466 are configured to be vertical.

As shown in FIG. 14B, the gripping mechanism 403 also comprises gripping devices 479 a and 479 b, wherein the gripping device 479 a or 479 b is a rigid component comprising a slotted hole 475 a or respectively 475 b, a bearing housing 474 a or respectively 474 b, a gripper 473 a or respectively 473 b. The surface of the gripper 473 a or 473 b on one side is configured to match the union of the surfaces 182 f, a lower section of the surface 182 e and a top section of the surface 182 g; wherein the surfaces 182 e, 182 f and 182 g are parts of the surface of the food container 182 shown in FIG. 6A-6C. In particular, the surface of the gripper 473 a or 473 b comprises a part 470 e, which is configured to be a part of a cylindrical surface, wherein the radius of the said cylindrical surface is the same or nearly the same as the radius of the partial cylindrical surface 182 e. Similarly, the surface of the gripper 473 a or 473 b comprises a flat part 470 f which is the same or nearly the same as the flat surface 182 f; and the surface of the gripper 473 a or 473 b comprises a part 470 g, which is a part of a conical surface, which is the same or nearly the same as the said top section of the surface 182 g.

As shown in FIG. 14C, two bearings 461 and accessories are configured to connect the bearing housing 474 a of the gripping device 479 a and the shaft 462 a, so that the bearing housing 474 a (or equivalently, the gripping device 479 a) is constrained to rotate relative to the shaft 462 a, or equivalent relative to the support component 464, around the axis of the shaft 462 a. Similarly, another two bearings 461 and accessories are configured to connect the bearing housing 474 b of the gripping device 479 b and the shaft 462 b, so that the bearing housing 474 b (or equivalently, the gripping device 479 b) is constrained to rotate relative to the shaft 462 b, or equivalently relative to the support component 464, around the axis of the shaft 462 b. Furthermore, the wheel 469 mounted on the shaft 463 a (or 463 b) is configured to be placed in the slotted hole 475 a (or respectively 475 b) of the gripping device 479 a (or respectively 479 b), so that a movement of the shaft 463 a (or 463 b) may induce a rotation in the gripping device 479 a (or respectively 479 b) around the axis of the shaft 462 a (or respectively 462 b). The motor 92N may induce a rotation of the rigid component 471 around the axis of the shaft 489. Hence the shafts 463 a and 463 b both of which are rigidly connected to the rigid component 471 are rotated around the axis of the shaft 489. Thus, the motor 92N may induce simultaneous rotations of the gripping devices 479 a and 479 b as to grip or release a food container 182. The rotations of the gripping devices 479 a and 479 b are configured to be in opposite directions. Since the gripping devices 479 a and 479 b are rotated, the grippers 473 a and 473 b may grip or release a food container 182 wherein the food container 182 may hold a cooked food. When the gripping devices 479 a and 479 b grip a food container 182, the surfaces 470 e, 470 f and 470 g on the surface of the gripper 473 a (or 473 b) are configured to touch or nearly touch the surfaces 182 e, 182 f and respectively 182 g of the exterior surface of the food container 182. In addition, when the food container 182 is gripped by the gripping devices 479 a and 479 b of the gripping mechanism 403, as shown in FIG. 14C, the food container 182 is configured to be positioned upright as to be able to hold a cooked food.

The gripping mechanism 403 also comprises proximity switches 91Q and 91R, targets 455 a and 455 b both of which are rigidly connected to the rigid component 471. The proximity switch 91Q is fixedly mounding on the connecting component 468 and the proximity switch 91R is fixedly connected to the support component 464 via a connector. As shown in FIGS. 14A, 14C, the motor 92N is connected to the computer 901 via wires 94N. The computer 901 may be configured to dynamically control the timing and/or speed of the motor 92N. As shown in FIG. 14A, the proximity switch 91Q is also connected to the computer 901 via wires 93Q, so the computer 901 may receive electric or electronic signals from the proximity switch 91Q. The proximity switch 91Q monitors the targets 455 a and 455 b when the targets are rotated with the rigid component 471 by the motor 92N. When the rigid component 471 is rotated by the motor 92N to a first position where the proximity switch 91Q senses the target 455 a, the pair of gripping devices 479 a and 479 b is gripping a food container 182. Similarly, when the rigid component 471 is rotated by the motor 92N to a second position where the proximity switch 91Q senses the target 455 b, the pair of gripping devices 479 a and 479 b is releasing? the food container 182. Each time the rigid component 471 is rotated to the first or second end position, the computer 901 may send signals to the motor 92N as to control the rotation of the motor 92N.

It should be noted that a rubber or silica gel or other elastic material may be attached to the gripping devices 479 a and 479 b.

(It should be noted that a pair of bearings may be configured to connect the input shaft 499 a and the bearing housing 495, so that the shaft 499 a is constrained to rotate relative to the bearing housing 495, or equivalently, relative to the support component 494, around the axis of the shaft 499 a. Similarly, bearings may be configured to connect the output shaft 499 b and the bearing housing 492, so that the shaft 499 b is constrained to rotate relative to the bearing housing 492, or equivalently, relative to the support component 494.) Thus, the motor 92Q may drive the rotation of the input shaft 499 a of the Geneva mechanism 493 relative to the support component 494. Since the rigid component 513 is rigidly connected to the output shaft 499 b, the rigid component 513 is also constrained to rotate relative to the support component 494 around the axis of the output shaft 499. In summary, the motor 92Q may induce an intermittent rotation of the rigid component 513.

The rotational motion mechanism 405 also comprises a proximity switch 91S fixedly connected to the bearing housing 495 via a connector; and a target 459 rigidly connected to a crank of the Geneva mechanism 493, and two targets 458 a and 458 b both of which are attached on the rigid component 513.

As shown in FIG. 14E, the proximity switch 91S is also connected to the computer 901 via wires 93S, so the computer 901 may receive electric or electronic signals from the proximity switch 91S. Each time the crank of the Geneva mechanism 493 is rotated to a position where the proximity switch 91S senses the target 459 and the electric or electronic signals of the proximity switch 91S are sent to the computer 901, the computer 901 would send signals to the motor 92Q as to control the rotation of the motor 92Q. At each stop of the rotation, the rotational motion mechanism 405 may complete a corresponding process.

The computer 901 may be configured to dynamically control the timing and/or speed of the motors 92P and 92S. As shown in FIGS. 14A and 14G, the proximity switches 91R and 91U are also connected to the computer 901 separately via wires 93R and 93U, so the computer 901 may receive electric or electronic signals from the proximity switches 91R and 91U. The proximity switch 91R of the gripping mechanism 403 monitors the targets 457 a and 457 b when the gripping mechanism 403 is slid along the axis of the screw shaft 482 by the motor 92P. Each time the proximity switch 91R senses the targets 457 a or 457 b, the computer 901 may send signals to the motor 92P as to stop the rotation of the motor 92P for a time period. Similarly, the proximity switch 91U of the transfer sub-mechanism 404 monitors the targets 458 a and 458 b when the proximity switch 91U is slid with the transfer sub-mechanism 404 by the motor 92S. Each time the proximity switch 91U senses the targets 458 a or 458 b, the computer 901 may send signals to the motor 92S as to stop the rotation of the motor 92S for time period. At each stop of the rotation of the motor 92P or 92S, the transfer apparatus 420 would complete a corresponding process. As explained before, the computer 901 may control the rotation of the motor 92Q according to the electric or electronic signals of the proximity switch 91S. Thus, the transfer apparatus 420 may be controlled by the computer 901 to grip a food container 182 and move it linearly in vertical direction of the axis of the screw shaft 482, or linearly in horizontal direction, or horizontally by an intermittently rotation around the axis of the shaft 499 b, or by a combination of them, and then it may release the food container 182 at a position which is different from the previous position.

A rigid component may comprise one or more of the following: a bar, a tube, a beam, a plate, a board, a frame, a structure, a bearing housing, a shaft. A rigid component can be made by metal such as steel or aluminum, or a mixture of metals, an alloy, a reasonably rigid plastic, a wood, or by other materials, or by a combination of several types of materials.

Similarly, a rigid connection of two or more components can be a connection which has some degree of rigidity in an application, and there is no strict quantitative requirement for the degree of rigidity. A rigid connection may be a welding of two or more metal components. A rigid connection may be a bolting of two or more components; and so on. Clearly, a typical connection of a shaft and a bearing housing by a bearing (and accessories), for example, is not a rigid connection, since the shaft can rotate relative to the bearing housing.

A support component described in the present patent application can be a rigid component of any type, or a plurality of rigid components which are rigidly connected to each other. A support component may be moved or fixed relative to the ground. A link described in the present patent application can be a rigid component of any shape, or a plurality of rigid components which are rigidly connected to each other.

Most common bearings are ball bearings and roller bearings. However, a bearing in the present patent application can be of any type.

Only a few examples and implementations are described. Other implementations, variations, modifications and enhancements to the described examples and implementations may be made without deviating from the spirit of the present invention. For example, the term cooking container is used to generally refer to a device for containing or holding food ingredients during cooking. For the purpose of present patent application, a cooking container can be a wok, a pot, a pan, a cookware, a bowl, a container, a board, a rack, a net, etc. The cooking also is not limited to any particular ethnic styles.
